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.

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

Inherited from Logger:

Method logPrefix Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
The file descriptor for the end of the pipe which can be written to wake up a reactor monitoring this waker.
The file descriptor which should be monitored in order to be awoken by this waker.
