Mark Thomas updated POOL-93:
----------------------------
Attachment: pool-93-markt-v2.patch
I have attached a new patch that incorporates the proposed fix for POOL-108.
This makes the assertOpen() test occur in a thread safe manner. POOL-108
patched GOP, this patch ports the same changes to GKOP.
On a similar note, I forgot to mention that the previous version also included
changes so the use of isClosed() was thread-safe.
v2 of the patch should now be a complete patch for the sync improvements
suggested here and for POOL-108.
> Reduce contention by making borrow & return more independent from each other

> least the factory-based validation & destruction can be handled
> independently. A few simple changes narrow the synchronization blocks yet
> retain overall correctness.
