Problems with threads and embedding

Hi,

i wrote a module for ctrlproxy which embedds python and provides an api
that ctrlproxy is scriptable.

Every script is started in an own interpreter instance and registers
some callback functions for different events.
The module is threadsafe and everything works just fine, with one
exceptions, dead threads are not removed from the process list.



import time
import thread
import sys
import os

def runme():
time.sleep(2)
print "PID: %s" %(os.getpid())
print "PID: %s" %(os.getppid())
print " ------------ END -------------"

print thread.start_new(runme,())


Results in:

I tried to spend time in every created thread through the advanced
debugging api, but this changed nothing. I experimented with the
sys.exitfunc without success.


I added some debugging function to see what happens.

IS is a interpreter state and TS a thread state.
16386 seems to be the thread created by the script. After it exists,
Python knows nothing about the thread anymore, but the return code
didn't seems to be catched.


The sourcecode is to large and CVSweb currently broken...
I uploaded the code @
http://files.poelzi.org/tmp/ctrlproxy_python/

http://files.poelzi.org/tmp/ctrlproxy_python/python.c is the main file.


Any hints for me so solve this anoying problem ?


regards
