I know that, of course. But try this: Remove the signal(SIGPIPE, SIG_IGN) and run the test suite. There is not a single failure. IOW, we don't have a single test case that verifies that the signal(SIGPIPE, SIG_IGN) is needed. I would like to have that test case, and you seem to know how to construct it (otherwise there wouldn't be so much buzz about it).
