Background actors can only be used in limited circumstances:
* ``PBackground`` only supports the following process connections (where
ordering is parent <-> child): main <-> main, main <-> content, main <-> socket
and socket <-> content.

* All parent background actors run in the same thread. This thread is
dedicated to serving as the worker for parent background actors. While it has
no other functions, it should remain responsive to all connected background
actors. For this reason, it is a bad idea to conduct long operations in parent
background actors. For such cases, create a top level actor and an independent
thread on the parent side instead.

* Background actors are currently *not* reference-counted. IPDL's ownership
has to be carefully respected and the (de-)allocators for the new actors have
to be defined. See `The Old Ways`_ for details.

A hypothetical layout of ``PBackground`` threads, demonstrating some of the
process-type limitations, is shown in the diagram below.
