[issue1975] signals not always delivered to main thread, since other threads have the signal unmasked

Well, the signals /are/ delivered as far as Python code is concerned. I
don't think Python makes any promise as to the delivery of signals at
the C level.
(actually, the best promise we may make is not to block signal delivery
at all, so that third-party libs or extensions relying on threaded
signal delivery don't break)
