Pythoin MUD (PyMUD?)

[Mike C. Fletcher]

In stackless, what you could do is establish a policy that any given
micro-thread cannot run longer than user.max_timeslices_per_thread (or
whatever you name it), then alter uthread.py's inner loop to enforce that
policy.  Your other threads would still get their timeslices while the bad
thread runs, and the wizard would get a "QuotaExceeded" error raised in
their micro-thread if it goes too far. Getting that error, they either
recode their loop or petition for a quota increase.

Enjoy yourselves,
Mike

Stackless could be a solution. Pre-emptively scheduled
microthreads. Your drunken wizard's code still runs forever,
but other things can happen at the same time.
