It doesn't work,
because we need also re-raise KeyboardInterrupt in
ThreadPool::worker_thread_callback()
...
try:
runnable()
except:
...
but all these exceptions are handled in
C:\Python25\Lib\threading.py
Thread::__bootstrap()
...
try:
self.run()
except:
...
and do not come to serve()
Maybe we can stop server manually,
without exceptions,
adding
self.running = False
to this handler:
ThreadPoolMixIn.handle_error():
exc_class, exc, tb = sys.exc_info()
if exc_class is ServerExit:
# This is actually a request to stop the server
raise
return super(ThreadPoolMixIn, self).handle_error(request,
client_address)
?
