Previously available in Concurrent Haskell, living here from GHC-7.6 on. This function merges incoming lists non-deterministically into one result. Its implementation in this module follows the pattern of the previous one from Control.Concurrent, but uses the old simple semaphore implementation, and optimises the case of only one remaining list.
