Then I expect everyone to volunteer to test the patch <wink>.

I just made a patch while running my final tests, so I have a pretty solid
proof that what I sketched was implementable <wink>. It's exactly the
scheme I described, and the coding went smoothly because it was something
that could be (and was) fully thought-out in advance. That doesn't rule out
conceptual or coding errors, though.
Now I'll stop typing until I know whether all the tests pass ...
OK, here's the patch:
I asked especially for Neal's (Mr. GC) and Fred's (Mr. WeakRef) reviews, but
all reviews are welcome.
