A previous change introduced a call to pthread_sigmask() in order to block SIGPIPE in a thread. Since there are no signal facilities on Windows that are similar to POSIX signals, just ignore the request to block the signal. In the particular case, the effect of blocking SIGPIPE on POSIX is that write() calls return EPIPE when the reader closes the pipe. This is how write() behaves on Windows.
