David Jencks closed GERONIMO-2077:
----------------------------------

    Resolution: Fixed

Fixed in openejb rev 2662.

Moral of story: be sure to clean up pool entries BEFORE returning them to the pool, not after
they have been checked out and put in use by another thread.

As a warning to others, here's the change:
