Right. I was working on a fix for that for a different reason. What we
really want is a check for such a timer on a transition from SIGIGN to
another state.  This would allow us to drop the ugly auto rearm code
for ignored timers completely. I had some working proof of concept
code, but got distracted. Need to find it again and dust if off.

That is certainly what came first to mind.  (Note that it's not strictly
SIG_IGN alone, but sigaction_says_ignore.)  We'll have to contemplate a lot
of corners to be sure we get it right.  It's not real clear to me how you
go about finding all the affected timers sanely from sigaction.

My idea was to dequeue the timer signal and put it into some separate
"check me on unignore" queue. That's the easy part. The nasty part is
to rearm the timer without running into locking madness.
