I don't know the general newsgroup name, but:
gmane.comp.python.scientific.user
or gmane.comp.python.scientific.devel
on news.gmane.org are the places I watch for scipy stuff.
As to the worker problem, a standard line of attack is a queue of
work-to-do tasklets, with each worker going back for more when he
finishes. The slowest running worker should then only be finished
after the fastest worker by at most the longest-running tasklet's time.
