Slice thread pool breaks down under high concurrency 
-----------------------------------------------------

                 Key: OPENJPA-1648
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1648
             Project: OpenJPA
          Issue Type: Bug
          Components: slice
            Reporter: Pinaki Poddar
             Fix For: 2.1.0


Slice thread pool breaks down under heavy usage [1].
This is due to poor choice of thread pool.

Also creation of thread pool for every flush() is inefficient.

Simple solution will be to use a cached thread pool -- which will be upper bounded by available
system's capacity for concurrent native threads.
