wow. i was performing my testing in a artificially created environment
where program did nothing but symlink resolution. it's nice to hear
that this change has substantial effect in real-life situation.

and i can't but attribute a part of this speedup to Chris' ongoing
effort to implement true vfork() in cygwin.
