Commit summary for MediaWiki.r110073:

Further reduced RTTs in SwiftFileBackend by making "file already exists" checks use the stat cache,
typically already set in FileOp::doPrecheck(). FileBackendBase::doOperationsInternal() already
clears the cache after locking (and before FileOp::attemptBatch) for consistency.

Tim Starling's comment:

Optional boolean parameters which default to false are one of the few acceptable applications of empty().
Aaron added lots of them in the FileBackend project, probably just to annoy empty-haters ;)
