We should make clear that the python callback can't keep any reference
to the domain.
Maybe the solution is to pass a name or UUID string and let the python
user do the lookup, might also avoid the object duplication (but then
the user will do the dictionary of domains and get into the same
problems of object lifetime).... I hate asynch interfaces :-)
If the callback keeps a reference, then python will reference count it, and this will not
get garbage collected until it gives up the last reference... am I misunderstanding
something?
