sbcl-0.9.4 released

sbcl-0.9.4 has been released; enjoy.

from the NEWS file:
changes in sbcl-0.9.4 relative to sbcl-0.9.3:
  * new port: the Solaris operating system on x86 processors is now
    mostly supported, though some rough edges in the environment
    remain.  (thanks to Daisuke Homma)
  * enhancement: SBCL on MIPS platforms now has a much larger dynamic
    space for its heap.  (thanks to Thiemo Seufer)
  * optimization: SBCL on MIPS platforms now supports dynamic-extent
    closures.  (thanks to Thiemo Seufer)
  * minor incompatible change: eof selects abort in the debugger.
  * minor incompatible change: *INVOKE-DEBUGGER-HOOK* is run before
    *DEBUGGER-HOOK* => *DEBUGGER-HOOK* is not run when the debugger
    is disabled.
  * minor incompatible change: SB-KERNEL:INSTANCE-LAMBDA is
    deprecated, and will go away in a future revision of SBCL.
  * minor incompatible change: GC-ON and GC-OFF are no longer
    implemented with a counter, it does not matter how many times gc
    is switched on or off
  * bug fix: discriminating functions for generic function classes
    with non-standard methods for COMPUTE-APPLICABLE-METHODS no longer
    make invalid assumptions about method precedence order.  (reported
    by Bruno Haible)
  * bug fix: TRUNCATE now correctly signals division by zero on MIPS
    platforms.  (thanks to Thiemo Seufer)
  * bug fix: degree sign (<U00B0>) could not be encoded in KOI8-R.
  * bug fix: correct pathname printing with printer escaping is on.
    (thanks to Kevin Reid)
  * bug fix: complex VOP definitions in "user-space" no longer trigger
    package locks.  (reported by Zach Beane)
  * fixed bug 343: SB-KERNEL:INSTANCE-LAMBDA is no longer necessary
    for funcallable-instance functions, and is no different from
    regular LAMBDA.
  * bug fix: PARSE-INTEGER no longer depends on the whitespaceness of
    characters in the current readtable.  (reported by Nicholas Neuss)
  * bug fix: SUBTYPEP on various CONS types returns more a more
    accurate acknowledgment of its certainty.
  * optimizations: REMOVE-DUPLICATES now runs in linear time on
    lists in some cases.  This partially fixes bug 384.
  * flush all standard streams before prompting in the REPL and the
    debugger.
  * bug fix: signal handling and triggering gc do not conflict
    directly anymore, in particular a high frequency sb-sprof does
    not prevent gc from running
  * bug fix: DECODE-UNIVERSAL-TIME now uses a more reasonable
    approximation for timezone and DST information between the
    universal time epoch and the smallest negative 32-bit time_t.
  * bug fix: ENCODE-UNIVERSAL-TIME no longer errors when passed the
    year 1899 so long as the encoded time is non-negative.
  * bug fix: on the x86 platform, SB-ROTATE-BYTE:ROTATE-BYTE returns
    the correct answer for non-constant rotate amounts when performing
    an inline 32-bit rotation.
  * threads
    ** bug fix: RELEASE-FOREGROUND doesn't choke on session lock if
       there is only one thread in the session
    ** bug fix: memory leak for streams created in one thread and
       written to in another
    ** bug fix: lockup when compiled with gcc4
    ** bug fix: race that allows the gc to be triggered when gc is
       inhibited
    ** bug fix: one less memory fault in INTERRUPT-THREAD, again
    ** bug fix: gc and INTERRUPT-THREAD don't hang when the RT signal
       queue is full
    ** bug fix: finished threads are gc'ed properly
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** CALL-NEXT-METHOD signals an error (in safe code) when the call
       has arguments with a different set of applicable methods from
       the orignal arguments.
    ** The type error thrown by MAP now has a correct expected-type
       cell.
    ** DISASSEMBLE now throws a TYPE-ERROR when its argument does not
       name a compiled function.
    ** Three MISC tests where a large bignum was improperly coerced to
       a float that couldn't represent that bignum during type
       derivation were fixed.
    ** SUBTYPEP can now handle types involving the negation of a
       list-form FUNCTION type.
    ** SUBTYPEP also now handles certain COMPLEX type specifiers such
       as (COMPLEX (AND RATIO (NOT FIXNUM))).
    ** READ-BYTE and WRITE-BYTE no longer take stream designators.
