I'm having trouble with sessions and threads.....
Do you mind if we move to having explicit sessions in microfacts? It
would seem to solve the problem I'm experiencing where sqlalchemy
bitches that my object:
"'X' is already attached to session 'Y' (this is 'Z')"
I regenerate this problem when I create from my web browser a second
thread or a second factlet after having previously restarted paster.
That is, when the create mode class makes a call to
session.save(new_entity) only the first create request is successful,
and succeeding requests all fail with this error. With the call is not
made, the created object is never persistent, but there is no error.
Is the current model session config the Pylons project initial default,
ie what paster pastes? We're having problems, so let's make it explicit?
