I've noted before that it doesn't make much sense to invoke GC unless there is at least one deallocation; you can't reclaim anything if there are no DECREFs.

It's easy to add a decref counter. It doesn't seem to help much though based on my limited testing. The standard test suite does not trigger it. I can't get our web application to either. Is it worth checking in? Maybe someone can come up with a better trick.

Note that we must take into account generations as well. If threshold0 is low then there are lots of quick collections. Setting it larger does not help too much as new objects will eventually be examined (unless they are destroyed before the next collection).
