def test_many_relationships(self):
"""
A test in which a drop is related to many other drops that live in a
separate DM (and thus requires many Pyro connections).
Drop A is accessed by many applications (B1, B2, .., BN), which should
not exhaust resources on DM #1 (in particular, the pyro thread pool).
We collapse all into C so we can monitor only its status to know that
the execution is over.
