I always heard (from you :-)) a patched version is needed on windows,
which is inconvenient for most users.

I am using with emacs-helm "grep -R" since two years now and more
recently "ack-grep" with success on GNU/Linux.
I don't know how fast is find/xargs but using "grep -R" is already fast
enough for most of the tasks.
Using "ack-grep" is always faster than grep even if in theory it is slower than
grep (It do not parse uninteresting files/dirs by default).
