Does this mean they work when you run the tests from cygwin, or that you
haven't tried it there? I've always run it with the defualt, which
should be unlimited, with no problems.
Could it simply be another issue with the infamous stdout/stderr
buffering on the msys console, that causes the script to get results in
the wrong order or something? [assuming this *is* a client-side problem,
of course]
