[Jython-users] kill a timed out python script in multithreaded Jython environment

[Mitch M <mit...@ho...>]

ok, pretty new to python. in new job, took over some code, basically,
it spawns a LOT of little python scripts. parent java program is
multi-threaded.

Current code wraps pythonInterpreter into class which synchronizes
exec() method. Comments says he did this because was concerned about 
threading.

first, is this a good idea? comments?

Anway, we occassionaly seem to be having a "dead thread" and I
wondered if one of these python scripts is getting into an infinite
loop or something (before you say "go look at them" there are hundreds
and hundreds executing over and over. it's not even really an option
to log each entry/exit. The logs are just too huge. It would kill
performance, which is already a problem in production and it only
occurrs in production.. So my thought was to put a timer (maybe launch
a class which sleeps and then kills the thread once the scripts executes) 
and then kill the nonresponding python script.

So how do I do this. I see a PySystemState.exit() but this is a STATIC
method. So wouldn't it kill ALL executing scripts (remember, even
though this method is synchronized, there are other java threads, so
wouldn't there be others executing?).

Any thoughts/opinions  would be appreciated.
