Hi Gustavo,
First of all, thank you for catching this.
For now, I've tried to extend GC to support closures.
You can find the proposed patch at https://bugs.php.net/bug.php?id=60139
However it won't work for other classes, anyway.
Probably it would be better to extend object handlers in 5.4 with some
uniform GC related callback, but for now I don't see how it should look
like.
Any ideas are welcome.
Thanks. Dmitry.

The garbage_collector currently only looks for relationships of objects by
calling get_properties. This causes noncollectable cycles in many internal
classes and several bug reports (the latest of which is
https://bugs.php.net/bug.php?id=60139 ).
The only solution I found so far is very very hacky and I'm not completely
convinced it works properly:

Do you think it would be possible for you to extend the current object
model and possibly the garbage collector to handle these situations before
5.4 (or give me some pointers)?
