intended to verify that SIGPIPE is delivered to a process writing or sending on a socket that has been shut down for write. If available, SO_NOSIGPIPE is also tested. This regression test is currently passed by RELENG_4, but not by HEAD or RELENG_5, due to a bug in the write() code for sockets. SO_NOSIGPIPE is not present in RELENG_4, however, so is not tested there. Reported by: Mikko Tyolajarvi <mbsd at pacbell dot net> PR: 78478
