Well, I just tried, and I can reproduce a hang with this:

  while :; do quer; done >& /dev/null

It happens with 1.5.18 and the current snapshot.  I didn't check the
1.5.18 version since I was too lazy to regenerate my copy with symbols
but the snapshot version "hangs" in sigsuspend, apparently waiting for a
SIGCHLD.  Since the process has no children, it is going to hang
forever.

So, this case, at least, is not a regression and it is not clear that it
is a cygwin problem.
