Either of these is certainly possible, and I agree that forkBlockedIO is more generally useful than my forkCatchIO. One tantalising possibility is that we could make forkIO have the forkInheritIO behaviour without breaking much code, since I bet forkIO is almost never called inside block. Cheers, Simon
