It is pretty much impossible to make sure on bailout (including exit() and errors) that all of the reference counts of the variables will go down to 0 even if we clean the call stack. This is due to necessary internal locking of variables in Zend.

    i don't understand why we cant go thru the call-stack and
    del-ref all the arguments? we're shutting down anyhow -
    right?

    also i'm *not talking* about bail at all - bail dosn't work
    anyhow - and there's no good way to fix it IMHO. but what
    needs to work is calling exit() from a function if there are
    resources somewhere on the stack.

Because as I mentioned there might be locked variables which aren't in the call stack. This is what I could think of right now but there might be other problems too.

I think we need to think of a better way to handle resource shutdowns (maybe with priorities).

    this will be major headache, right?

    don't get me wrong, but i need this to get fixed elsewise
    using refcounts for dependicies is simply not working and i
    would have to think of something different - which would be a
    real shame.

Don't get me wrong. I really want to help you :) I just can't think of a great way right now. The only thing I could think of is making the resource shutdown smarter (will probably be quite a bit slower though). Andi
