QObjectCleanupHandler could potentially be very useful, though I or
someone else would need to look at how it works.  QObjects also need to
be deleted if they have no parent and no Python code references them,
though there may be exceptions to that rule.  PySide's typesystem files
are substantial and some of the code in them was added to handle special
cases.

But, my main point was all of this is Qt specific.  I was involved
somewhat with pygtk where many of the issues were the same, but the
mechanisms to solve them depended on the glib/GObject runtime rather
than the Qt/QObject runtime.
