>      Project: Carob
>         Type: New Feature
>   Components: C++ API
>     Versions: Carob 0.7.2

>      Fix For: Carob 0.7.3

>
>
> When deleting a connection, if no more connection parameters point to a 
> controller pool, this pool is deleted
> Thus, creating a new connection with same settings will create a new pool, 
> which will *not* remember which controller the last connection was connected 
> to.
> This is a problem for php, which deletes connections after each request. 2 
> subsequent request will then hit the same controller, without load balancing
> The solution is to cache the controller pools for a couple of seconds before 
> deleting it. This will lead to small memory leaks at the end of the process 
> (the last controller pool never being freed), which is not a problem as the 
> process is exiting (thus freeing its memory)
