Use two timers and sigwait rather than looking for EINTR.

The latter had a race condition whereby if the signal from the
fallback timer was delivered before the call to clock_nanosleep(), it
would be lost.  This was a fundamental problem with using asynchronous
signals, and switching to sigwait(), which can wait for blocked signals,
should solve it.
