-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: U{http://people.freebsd.org/~dwhite/PyKQueue/} |
- |
-Maintainer: U{Itamar Shtull-Trauring<mailto:twisted@itamarst.org>} |

- |
-You're going to need to patch PyKqueue:: |
