Due to the nature of classic google app engine, you can't leave threads running. This doesn't mean you can't have sockets open between requests, but the MongoDB driver wants to use threads to manage those sockets for you and that's a no-no.
This leaves you pretty much two choices if you want to use MongoDB in some capacity with Google App Engine: 1) Use Managed VMs. You can do almost anything you want in a Managed VM, including creating threads. 2) Hack the driver to not use threads. There really aren't a lot of other options. GAE is inherently constrained somewhat more than other platforms. There are advantages and disadvantages to this, but if you really want to make heavy use of MongoDB, I suggest investigating #1 above.
