One small possible revision to consider:  As I read the code, all
manipulation to pg_signal_queue is inside a CriticalSection, and it is
only set (> 0) when there are pending signals.

ISTM that pg_queue_signal can abort without calling QueueUserAPC
pg_signal_queue is already set.  This will keep the dispatch function
from getting called extra times.  Paranoia statement

pg_signal_queue = 0;

could possibly be added at the end of the dispatch.

Everything else looks good to me.  Looking at the code, pg_signal_queue
is better and simpler than the event based method I was suggesting, IMO.
