libghc-concurrent-extra-prof 0.7.0.12-2 (ppc64el binary) in ubuntu kinetic

 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.
 .
 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.
