concurrent-extra: Extra concurrency primitives

The concurrent-extra package offers among other things the following selection of synchronisation primitives:

• Broadcast: Wake multiple threads by broadcasting a value.

• Event: Wake multiple threads by signalling an event.

• Lock: Enforce exclusive access to a resource. Also known as a binary semaphore or mutex. The package additionally provides an alternative that works in the STM monad.

• RLock: A lock which can be acquired multiple times by the same thread. Also known as a reentrant mutex.

• ReadWriteLock: Multiple-reader, single-writer locks. Used to protect shared resources which may be concurrently read, but only sequentially written.

• ReadWriteVar: Concurrent read, sequential write variables.

Besides these synchronisation primitives the package also provides:

• Thread.Delay: Arbitrarily long thread delays.

• Timeout: Wait arbitrarily long for an IO computation to finish.

Please consult the API documentation of the individual modules for more detailed information.

This package was inspired by the concurrency libraries of Java and Python.
