Just giving you a status report:
I've just run 55 threads against my pool (configured to a max of 20
connections) and haven't seen any big problem. The only exception I've seen
was
java.lang.IllegalStateException: deque is full

Seems like a returnConnection phased tryed to add a connection to the pool
already filled. (Semaphore issue?)
