Category:         Parallelism
Synopsis:         Run jobs on a limited number of threads and support data dependencies
Description:
  The motivation for this package was to run computations on multiple cores
  that need to write intermediate results to disk.
  The functions restrict the number of simultaneously running jobs
  to a user given number or to the number of capabilities
  the Haskell program was started with,
  i.e. the number after the RTS option @-N@.
  .
  There are some flavors of this functionality:
  .
  * "Control.Concurrent.PooledIO.Independent":
    run independent actions without results in parallel
  .
  * "Control.Concurrent.PooledIO.Final":
    run independent actions with a final result in parallel
  .
  * "Control.Concurrent.PooledIO.InOrder":
    run jobs in parallel with data dependencies like @make -j n@
  .
  Related packages:
  .
  * @lazyio@: interleave IO actions in a single thread
  .
  * @async@: start threads and wait for their results, forward exceptions,
    but do not throttle concurrency with respect to number of available cores
  .
  * @parallel-tasks@:
