Code Issues Proposed changes

Disable the pymongo pooling feature for tests

Browse Source 
Because pymongo doesn't close connection on .close() when we use its
pool, we disable the MongoClient pooling feature for running tests.

This allow to use a normal number of connection in mongod for test.

Fixes bug #1218488
