Description
When TLABS are being sized to meet the allocation rates of each thread, statistics
are kept on the allocation rates for each mutator.  Dump that information so the user
can understand the allocations needs of a thread.
An MBEANS interface to get this information was also part of the request.

This is not on our list of current priorities. If this changes please re-open this issue. Closing as WNF.
