This just won't work on a front end request. Any thread you create will be
destroyed at the end of the request.
The appengine front end is not designed for this type of capabiltiy.
You could consider running your mongo interface on a managed vm, and then
use some sort of simple rpc mechanism to talk to this interface.
Alternately find a light weight connection service that only exists for the
duration of a request.
