I wasn't really making any decision here, just fixing a bug in the cabal
file versus the behaviour with the old build system.

Would the programmer really want a function that does nothing if timeout
functionality isn't available? It's not obvious to me. Perhaps there
should be an attemptTimeout function or something for that?

Indeed. It's currently earmarked for moving to a new concurrent package,
but that will still have partial functionality when compiled with hugs.
Solutions welcomed!


Thanks
