Hi,
I want to exit my application immediately when CTRL+C is pressed,
however reactor hangs when there are running threads.
Some of these threads have blocking I/O, so I can't simply set a
variable or wait for them to terminate. An example application would
be:
Python threads (being plain old operating systems; for example, POSIX
threads) aren't generally interruptable. You could try exiting the
entire process using `os._exit`.
This is the case whether you're using Twisted or not.

from twisted.internet import reactor, threads
from time import sleep
import signal
def do():
try:
sleep(10)
except KeyboardInterrupt:
print "interrupt!"
#def cleanup(signum, stackframe):
def cleanup():
d.cancel()
reactor.callFromThread(reactor._stopThreadPool)
reactor.callFromThread(reactor.stop)
if __name__ == '__main__':
d = threads.deferToThread(do)
#signal.signal(signal.SIGINT, cleanup)
reactor.addSystemEventTrigger('before', 'shutdown', cleanup)
reactor.run()
How can I achieve this?
