ghc-threads

Fork threads and wait for their result

This package provides functions to fork threads and wait for their result, whether it's an exception or a normal value. Besides waiting for the termination of a single thread this packages also provides functions to wait for a group of threads to terminate. This package is similar to the 'threadmanager', 'async' and 'spawn' packages. The advantages of this package are: * Simpler API. * More efficient in both space and time. * No space-leak when forking a large number of threads. * Correct handling of asynchronous exceptions. * GHC specific functionality like 'forkOn' and 'forkIOWithUnmask'.
