Confirming this. Going through and adding a session.commit() at the end of 
every function where I execute queries fixes the issue.

This *appears* to be madness. I can't imagine why one would want a mode of 
access to a database wherein queries are always run in a transaction. But I'm 
certainly willing to be convinced otherwise. :-)
