'C' will not necessarily be 'gio.FileMonitor' — I think the internals
of the GIO methods might further "subclass" it in some way depending
on what underlying monitors are available.

I've been avoiding this because it involves a lot of boilerplate: the
signals needs to be replicated and passed through, same for all
GObject properties, same for the usual methods. I'd basically have to
re-write the entire class in Python, and then tack on my methods.
Otherwise I have to write two sets of methods for anything that
touches this wrapped object.

Still, if it's the only way, sure.
