Try this. ext can be found in 'C Function in a Python Context' on
google groops.

extA[ 'araise' ]= r"""

int res= PyThreadState_SetAsyncExc( a, exc);
return res;
}
""", ("i","i","O")
LastCallException= type( 'LastCallException', ( Exception, ),
{ 'canstayhere': True } )
import thread
import threading
import time
partystart= threading.Event()
doorsclose= threading.Event()
def thd():
partystart.set()
try:
while 1:
print( 'running, ha ha!' )
time.sleep( .2 )
except Exception:
print( '\nclean thread exit\n' )
finally:
doorsclose.set()
partyid= thread.start_new_thread( thd, () )
partystart.wait()
print( 'waiting a second\n' )
time.sleep( 1 )
ret= extA.araise( partyid, LastCallException )
doorsclose.wait( 1 )
if not doorsclose.isSet():
