The self-pipe trick<http://cr.yp.to/docs/selfpipe.html>, used to wake up the main loop from another thread or a signal handler.

_FDWaker is a base class for waker implementations based on writing to a pipe being monitored by the reactor.

Method __init__ Initialize.
Method connectionLost Close both ends of my pipe.
Method doRead Read some bytes from the pipe and discard them.
Class Variable disconnected Undocumented
Instance Variable fileno Undocumented
Instance Variable i The file descriptor which should be monitored in order to be awoken by this waker.
Instance Variable o The file descriptor for the end of the pipe which can be written to wake up a reactor monitoring this waker.
Instance Variable reactor Undocumented

def connectionLost(self, reason): (source)
