Description Andreas Schneider 2013-07-11 12:57:44 UTC 
If a signal handler is registered and unregistered later, tevent_loop_wait() never finishes.

This is because tevent internally registers its own signal handler "sig_pipe_handler". This handler is never removed, which causes program to stuck in tevent_loop_wait() even if there are no custom handlers registered.
