Issue Type: Bug (was: Improvement)

ParallelExecutor service appears to be bound to the number of executor threads
specified by THREAD_POOL_CORE_SIZE )

> Key: TAP5-1563
> URL: https://issues.apache.org/jira/browse/TAP5-1563
> Project: Tapestry 5
> Issue Type: Bug
> Components: documentation, tapestry-ioc
> Reporter: Andy Blower
> Priority: Minor
>
> ParallelExecutor service is bound to the number of executor threads specified
> by THREAD_POOL_CORE_SIZE rather than THREAD_POOL_MAX_SIZE, which means by
> default only three parallel tasks are executed at once rather than the
> maximum of 20. This is unexpected behaviour for someone not familiar with the
> ThreadPoolExecutor design, which is not intuitive. The documentation of
> ParallelExecutor is very misleading and should be expanded to explain this
> correctly.
> This blog post I found explains it clearly:
