grep slows to a crawl

[Drew Adams]

I don't have an emacs -Q recipe for this.

I'm using a native Windows build with Cygwin grep (and bash shell).

When I launch a simple Emacs `grep' it starts out fast and then
progressively slows to a crawl. I don't see this problem with the
2005-06-26 CVS snapshot I have, or with Emacs 20 or 21.3.1.
