Part of twisted.internet View Source
A kqueue()/kevent() based implementation of the Twisted main loop.
To install the event loop (and you should do this before any connections, listeners or connectors are added):| from twisted.internet import kqreactor | kqreactor.install()
This reactor only works on FreeBSD and requires PyKQueue 1.3, which is available at: http://people.freebsd.org/~dwhite/PyKQueue/
Maintainer: Itamar Shtull-Trauring
You're going to need to patch PyKqueue:
