Linus, the fact that is not explained by your theory is why
Ctrl-Z+kill works but Ctrl-C doesn't. On the signal side these
both should be implemented in the same way -- if there was
really a missing signal_pending() check somewhere then Ctrl-Z
(and kill) should be delayed too.

Now doing faster signal processing is always a good thing in general,
but I'm a little doubtful your patch will help with that
particular problem.
