Hmm, sleepq_timedwait_sig() is supposed to react to signals.
At least that's what its description says:
/*
* Block the current thread until it is awakened from its sleep queue,
* it is interrupted by a signal, or it times out waiting to be awakened.
*/
int
sleepq_timedwait_sig(void *wchan, int pri)
{
int rcatch, rvalt, rvals;
rcatch = sleepq_catch_signals(wchan, pri);
rvalt = sleepq_check_timeout();
rvals = sleepq_check_signals();
thread_unlock(curthread);
if (rcatch)
return (rcatch);
if (rvals)
return (rvals);
return (rvalt);
}
