I found a problem with input_handler(). If a reference clock
passes a blocking file descriptor, input_handler can block
forever. Symptoms include but are not limited to UDP sockets not
working, several signal types being ignored, and the main loop
stopping in its' tracks. I've included a patch to handle it for
you, but there has to be a better way.
