[Haskell-cafe] Question about forkIO

Once control returns to f's caller, outside of the Haskell runtime,
then there isn't any way to dispatch IO threads - that's done by
the runtime, so it can happen only while executing in the runtime.
I am not a forkIO expert, that's just how it appears to me from my
limited understanding of how they work.

For extra credit - do the old IO threads resume if you call 'f' again,
so you'd have more each time?  (I don't know!)
