Karl Wright commented on CONNECTORS-638:
----------------------------------------
I found one possibility in the connection expiration code. If the database
handle close operation fails during connection expiration, and it fails by
throwing anything other than a SQLException, we could leak handles.
r1443521 fixes this potential issue.

> Reports of a leak of connection handles, shown because ManifoldCF winds up
> waiting to get a connection, and failing.
> The database in question so far always seems to be PostgreSQL, FWIW, and it
> has been proven that there is a connection handle leak, so that all the
