I've seen nasty behavior with grep that isnt' cygwin
specific. Try "pcregrep" and see if you have the same issue.
I found it to be about ~100 times faster under _some_ searches
though 2-3x is more typical. The gnu re-parser isn't real
efficient under some circumstances.
If you find a big difference, you might also want to report
it to the bug-g...@gnu.org mailing list, but last time I did,
they told me "that's the way it is" due to some posix conformance
thing...
