This is a cool beast! I wonder where the computing industry would be today 
if this was a POSIX interface on memory management ;-)

Some questions:

What happens if multiple contexts have references to a pointer and the 
pointer is freed? I assume it then becomes child of one of the contexts 
having references to it.

Or put in another way what is the difference between references and being 
a child to a context? Unless I am mistaken this is primarlily an internal 
distinction from the internal talloc design and not really important to 
the callers, right?

And is there an example on in what kind of situations it may be desireable 
to have control over who becomes the parent when the original pointer is 
freed?


In addition would you mind talloc being borrowed by some other GPL 
projects? (credits given where credits due ofcourse)
