I'm communicating with a PolyML program over stdin/stdout, and the "Increasing stack" messages were gettiong in the way. They are currently sent on stdout, but I believe they should be sent to stderr (or there should be the possibility of switching off warning messages altogether).

Thanks to PolyML being open source, it was easy to make a small patch to processes.c in the driver to achieve output on stderr. David Matthews suggested I post it here in case it is of interest to others. I hope the patch may be integrated (or improved upon) in a later release.
