It should be "class Klass:". This code has never been tested. The MSSQL
(Dave Rogers) often splits off from the CVS repository and it takes weeks
or months to reel him back in. I added this change, but don't have MSSQL to
test with.
The fix is checked in now.

BTW that class is picked up by MK as a mix-in. Its methods are injected
into the real Klass located in MiddleKit.Core. This mix-in technique makes
it convenient for the specific object stores to customize MK without having
to subclass.

No, this comes up quite a bit, but no one has tackled it.
We also haven't tackled the DB pooling issue (in MK) yet. I'm thinking
there could be some relation between MK and Webware.MiscUtils.DBPool but I
haven't followed it through.
