* fork.cc (fork): Honor error return from sig_send. Don't continue with fork
if we couldn't suspend signals.
* sigproc.cc (sig_send): Set sigCONT event when we see __SIGNOHOLD.
(wait_sig): Remove holding_signals. Create pipe with a buffer which will
theoretically cause blocking if there is nothing reading on the pipe. Wait for
sigCONT at end of loop when we have a __SIGHOLD.
