me hacking on libevent-python
libevent-python is a CPython extension module that wraps the lightweight C library 'libevent', available at http://www.monkey.org/~provos/libevent/.
libevent provides a unified interface to a variety of IO multiplexing mechanisms (select, poll, kqueue, epoll) and an event loop that supports timed events and signal handlers.
For usage examples, see the examples/ directory, which should grow as libevent-python matures.
