can confirm, don't try passing Session objects as arguments over
multiprocessing. that's not going to work for many reasons. new child
process should use its own session.

I haven't used the multiprocessing library, but if it uses pickle to
transfer SQLAlchemy objects, it's going to be difficult to make it
work. Objects loaded via the SQLAlchemy ORM hold a references to the
Session that was used to load them, which in turn holds a reference to
a database connection.
