Changes for version 0.22
- Fixed problem in random access test-suite that would fail only on faster machines.
- Increased Makefile.PL dependencies for Thread::Conveyor and Thread::Conveyor::Monitored.
- Added support for throttling Conveyor belts. Removed local throttling support, as it now uses the throttling support of Thread::Conveyor. This means that now monitoring belts will be throttled the same way as the job belt (they were not throttled before).
- Thread::Pool - group of threads for performing similar jobs
