[concurrency-interest] Class striped/ordered Thread Pool

Not sure if this makes sense unless you use a SingleThreadExecutor per
stripeClass. Otherwise you have races in the submission of StripedRunners of
the same stripeClass, and even if you order the queue so that they start
execution in the right order, you can't guarantee what order they will
complete in. Unless it is all done by a single thread.

  Subject: [concurrency-interest] Class striped/ordered Thread Pool


  Hello all,

  I'm looking for a thread pool with the following characteristics... (in
pseudo-code)

  interface StripedRunner {
      Object getStripeClass();
      void run();
  }

  magicPool.execute( stripedRunner );

  The idea being that any StripedRunners with the same stripeClass would get
executed in the order they were queued,
  but StripedRunners with different stripedClasses could execute
independently.

  Is there a way to configure the standard concurrent pools to work this way
(doesn't seem to be), or a way to extends
  the current code?

  Or perhaps some third party library implementation?

  Thanks!

  Glenn McGregor
