ROTFL. That's one way to get someone to dedicate time to something ;). Sander

Oh, except ofcourse when you are going to take allocators into account. I'm not so sure you want to have memore be allocated from one allocator and freed to another... So you would need to restrict that. Sander

USE AT OWN RISK!' feature, since you are going to mess with lifetimes and such (and cleanup ordering since the child cleanups happen at a different time than at original parent destroy). Be careful with lifetime dependencies. > We are considering the use of APR memory pool feature in our > commercial product but I have not been too impressed with the support > out there. Excuse me? This is exactly the sort of comment that demotivates me to write the actual patch. Sander

There's not really a good way to move a subpool... or at least none I'm aware of. Sander could answer that with more certainty. But basically you'd have to individually move the items in the old subpool to the new subpool, which is not really a particularly easy thing to do. :-/ --Cliff
