Sigh, John looks like your fix broke something else.
I just ran a full test before checkin in some additional tests I
developed and I see:

test/test_mysql.py::mysqlSchemaTest::test_removeClassKey <-
test/db_test_base.py SKIPPED
test/test_mysql.py::mysqlSchemaTest::test_removeMultilink <-
test/db_test_base.py SKIPPED
test/test_mysql.py::mysqlSchemaTest::test_reservedProperties <-
test/db_test_base.py SKIPPED
test/test_mysql.py::mysqlClassicInitTest::testCreation <-
test/db_test_base.py FAILED
test/test_mysql.py::mysqlConcurrencyTest::testConcurrency <-
test/db_test_base.py FAILED

I don't have mysql running, and for a while it properly skips things
then .....

Are you running a full test suite when trying to validate
run_tests, or were you following my lead and only running the
indexer stuff?
