Couldn't you just substitute "catch exceptions" with "unsafePerformIO" here, and make the same argument?

This puzzled me, until I realized you meant `unsafeInterleaveIO'.

Aargh, yes of course! Sorry about that.

Assuming you mean unsafeInterleaveIO, not quite. GHC's scheduler is fair, so you are guaranteed after

forkIO $ a

that a's side effects will happen eventually.

Ah, I hadn't thought of that. -k -- If I haven't seen further, it is by standing in the footprints of giants
