Ugh, and I've just realized that this is ANOTHER thing that breaks my
error handling, because it means that if, for example, closing a
database cursor (in its __gc method) causes an error, that error will be
caught in the GC and not propagated, and there's no way out.

I understand that handling errors in GC is tricky, but having a place
where errors are caught and then ignored is a complete showstopper in an
environment where errors MUST be propagated up to a point where they can
be safely handled (and no, this can't be done inside the __gc method
itself).
