I seem to recall you saying that Vista added a fork-like facility to the kernel which might let Cygwin implement a copy-on-write fork(2).  Would dropping XP support allow that?

If so, that would probably speed Cygwin up quite a bit in many common use cases: running autoconf configure scripts, Makefiles, etc.
