What does "EINPROGRESS" or "EWOULDBLOCK" not exported by Errno.pm mean?

These are messages put out by starting cluster.pl under Windows with certain releases of Activestate perl.

The messages are warnings and can be safely ignored. They happen because Unix systems have these error condition names as synonyms for another error. Windows does not have them and so it complains about it on startup. The warnings are entirely benign.
