There evidently already is a timeout (according to Jim).  I think it's
set to 30 minutes.  I'm not sure where it is.  It's possible it needs to
be lowered.

No... at least I don't think so...  if you have a long-running method,
and some joker reloads that method 5 times (because they think it'll
speed things up), it will chew up five threads, and whatever processing
is happening will be happening five times.  It's likely that the Python
process would be working hard in this scenario... unless of course the
method was long-running because it was IO-bound instead of CPU-bound...
did requestprofiler turn anything up for you?
