Following discussion on the libraries list, I renamed forkOnIO to
forkOn. In due course we might want to also rename forkIO to fork.
I left the Int argument as it is, it's quite useful to be able to
specify a number to be interpreted modulo the actual number of
I also used the term "capability" consistently. It might not be the
best choice, but we have to pick something.
