OK, yea, I will use threaded.

Oh, yuck.  Would SIG_DFL be better here?  I am thinking of adding
sigblock into that code on the assumption that if they have signal(),
they have sigblock().  Should we disable threaded builds unless they
have sigaction()?

I suppose the sigblock() would take care of the pending signal problem
too.
