I'm sorry you're disturbed. ;-)

Not really.

You're right, TemporaryStorage should really support versions.  But it
doesn't; there wasn't enough time. :-(  Maybe in the future, but no
promises.  Note that you can put the data container in a versioning
storage and get around this problem now.

Re: TemporaryStorage ignoring versions. I think this might be OK for
some pattern of usage.  However, I can imagine receiving another email
from somebody saying "how dare your sessions ignore versions; this has
really messed me up and you've destroyed my project". ;-)  I'd probably
accept a patch however that allowed you to set an environment variable
to control this behavior.

Thanks!
