erm, can't you point multiple signal handler entries to the same
routine? can't you also make it so that signals aren't defered
or blocked while another handler is executing so you may actually
re-enter the handler before it's complete.
specifically how you say you increment it, then decrement it,
if you have multiple handlers where one can interupt another
you can have the counter get jumbled.
