Not sure this is all according to your taste, but having this would have helped me personally to stay out of your hair. :)

I think Hooks is the wrong location for this. contrib package may be a better fit

@parsonsmatt I think we just need one extension that adds --timeout=<seconds> and I guess some timeout combinator Timeout.apply :: Seconds -> SpeWith a -> SpeWith a (or maybe Timeout.seconds :: Seconds -> SpeWith a -> SpeWith a, not sure).

Either as a separate package or in -contrib.

I think that will supersum #889, #914, #918 and #927.

At some point @BebeSparkelSparkel wanted to look into it #890 (comment), but from what I understand it's still up for grabs.
