Guix

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.
