I've stubbed this mechanism here:
https://github.com/libgeos/libgeos/pull/52

Basically, once you don't need an explicit handle on your
GeometryFactory you can call its "autoDestroy()" method and
it will be destroyed once all the geometries referencing it
are also deleted.

Could be a key to what we're trying to do here.
