Reading the source code and the repository, it seems there has been a
*lot* of activity around this async stuff in the codebase, and you may
well get different test results with a more modern version of the
trunk.

ying to acquire a connection
gets issued aWorkerThread.interrupt() for taking too long. So
adjusting some timeout settings (to make Tomcat more patient
than the connection pool) should give a workaround. DBCP had
a better grasp of what was going on when reporting this.
