Yup.  You're right. I'm wrong (though only technically -- the  
"something not recommended" would indicate that I was conceptually  
right ... ;-).  Thanks for the pointer!

This also explains the behavior in Ronald's code.  It isn't a bug, it  
is a feature!

Since the code was deallocating the old pool after creating a new pool,  
the new pool was "above" the old pool in the stack and was therefore  
removed along with the old pool.
