It actually is the case that many, many headers get included in each source 
file.  Some are worse than others, of course, and this is aggravated by the fact 
that many headers files require other header files.

I believe that we could still get the precompiled header support without 
MakeDeps/includeDB (i.e, tradition includes), but there's a surprising amount of 
fondness for this system at this point.
