I may be off base here, but having investigated this type of problem
regarding a possible Python mud, Stackless Python and in particular
microthreads were mentioned. See: www.stackless.com

By the way, checking into the various Python muds (MOOs, etc) out there
may be interesting -- it would seem they'd need a way to cope with this
too.

Oh, and hi Stefan! We chatted at LinuxTag.
