- Importing testenv has no side effects- explicit functions provide similar behavior to the old immediate behavior of testbase
- testing.db has the configured db
- Fixed up the perf/* scripts
"engine_or_url", "bind_to", etc. are all present, but deprecated.
they all get replaced by the single term "bind". you also
set the "bind" of MetaData using
metadata.bind = <engine or connection>. this is part of 0.4
forwards compatibility where "bind" is the only keyword.
