This means quasi-finalizer: I mean finalizeClassLoader in classMethod.c,
specifically.

Yes. At least, I think so.

I may be wrong, though.

Actually, I think I'm probably wrong: if there's no object of that
class, and the class loader doesn't hold a reference, the class will
be gc'd.

Then loadClass() will give a duplicate name error, but the class
object you get through findLoadedClass is bogus.

So I think you're right, we need a connection from the classloader
to the class that is walked.
