:: [IO (Maybe a)] -> IO (Maybe a) -package:conferer

Run the list of computations in parallel, returning the result of the first thread that completes with (Just x), if any. Users of the global pool must call stopGlobalPool from the main thread at the end of their program. See also parallelFirst.

Takes computations returnings Maybes; tries each one in order. The first one to return a Just wins. Returns Nothing if all computations return Nothing.
