New tests in 0.4 cause MSSQL to hang

[paj]

A number of new tests cause hangs on MSSQL.

orm/unitofwork.py: test_update, test_multi_update
orm/session.py: test_transaction, test_autoflush, test_autoflush_unbound
engine/transaction.py: testnestedsubtransactionrollback, testnestedsubtransactioncommit, testrollbacktosubtransaction

Since changeset 3267 these are disabled for MSSQL, so we can at least run the unit tests. Some follow-up work is needed to actually fix the issues, or declare the features unsupported on MSSQL.

i fixed these the other day and tested on MS-SQL. put some more aggressive "connection teardown" in the tearDown methods and disabled nested transaction tests which dont apply to MS-SQL in 62410adeb9f6a0e01de35680ff77cc15ae994995.
