Proposal: System.Timeout module for base (Trac #980)

[Johannes Waldmann]

would this combinator help solve the following problem:

I have two (or more) threads (created by forkIO)
and each does an external ( System.Cmd.system ) call.
When the first of these returns, the others should be killed.

(when I try to kill the Haskell RTS threads,
the external programs still seem to continue).
