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 package 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.
