Comment (by nakal):

 As far as I know, SIGPIPE will occur, if a pipe was there, but it's closed
 later and the main process still tries to write to it. I think detached
 programs don't get SIGPIPE when they write something to stdout/stderr.

 I have to mention some more facts here. I tried to catch many more signals
 to check what happens. My small program originally did not catch SIGPIPE
 and the behavior is the same. You can try it.

 There is no endless loop when you send the signal. The process is still
 idle. I think that the main process still works correctly without
 interruptions, but I will verify it later to be sure.
