name:                async
synopsis:            Run IO operations asynchronously and wait for their results

description:
 This package provides a higher-level interface over
 threads, in which an @Async a@ is a concurrent
 thread that will eventually deliver a value of
 type @a@.  The package provides ways to create
 @Async@ computations, wait for their results, and
 cancel them.
 .
 Using @Async@ is safer than using threads in two
 ways:
 .
 * When waiting for a thread to return a result,
   if the thread dies with an exception then the
   caller must either re-throw the exception
   ('wait') or handle it ('waitCatch'); the
   exception cannot be ignored.
 .
 * The API makes it possible to build a tree of
   threads that are automatically killed when
   their parent dies (see 'withAsync').
 .
 Changes in 2.0.2:
 .
 * Add a Monad instance for Concurrently
 * Bump base dependency to allow 4.9
 .
 Changes in 2.0.1.6:
 .
 * Add workaround to waitCatch for #14
 .
 Changes in 2.0.1.5:
 .
 * Bump @base@ dependencies for GHC 7.8
 .
 Changes in 2.0.1.4:
 .
 * Bump @base@ dependency of test suite
 .
 Changes in 2.0.1.3:
 .
 * Bump @base@ dependency to allow 4.6
 .
 Changes in 2.0.1.2:
 .
 * Bump @stm@ dependency to 2.4
 .
 Changes in 2.0.1.1:

 .
 Changes in 2.0.1.0:
 .
 * Added a @Functor@ instance for @Async@
 .

 .
 * Added @mapConcurrently@
 .
