That patch was not about a leak.  It was about reducing the memory per 
session by dynamically allocating space for jids.

I don't think anyone has indicated that they have encountered a true leak.

Are you sure there actually *IS* a leak?  In other words, if you cycle 
between 100 and 700 users several times, does the peak memory usage 
continue to increase?

In other words, if you see something like this:

100 users  20 meg
700 users  140 meg
100 users  140 meg
700 users  140 meg
100 users  140 meg
700 users  140 meg

...there's no leak.  It's just not releasing unused memory.

A leak is if you see this:

100 users  20 meg
700 users  140 meg
100 users  140 meg
700 users  150 meg
100 users  150 meg
700 users  160 meg
