Because of the problems with a Sybase SA backend on both python-sybase
and pyodbc, I changed the poolclass to AssertionPool and found a bunch
of unexpected (to me) situations where AssertionPool failed. Based on
a casual examination of the code, it seems that one connection should
be sufficient most of the tests (apart, of course, from the ones that
test multiple connections). Is this assumption correct?
