Description
Whether or not the app has set a handler, a SIGALRM sent from another process seems to have no effect if the app has not set a timer. The signal is not blocked or ignored: the master_signal_handler is invoked, but returns without doing anything.
Is there a reason for this non-transparent behaviour?
