[I think this is similar to the FILE problem]

Which component could call this function?  I think in
some languages it is possible to register a procedure
with the GC, but I am not sure if that is possible in
all languages.

I think an implementation of high-level bindings must
"know" the cairo-internal connections anyway, at least
for the cairo types the implementation intends to
proxy.  But that doesn't necessarily mean that the
high-level proxy knows when a low-level resource can
be destroyed.  What happens for example if I call the
notification function(s) only during program shutdown?
