Stared at the code for a bit, and spent some thoughts on it. Makes sense.
I haven't actually tested this beyond "BB is green". The server testbed
will give it a bit of testing, but this is not really meaningful either
(because I have 3 clients connected at maximum)...
If the environment is very tight on memory, reducing --max-clients is
way more effective (and shrinks the hash map accordingly).
Your patch has been applied to the master and release/2.7 branch
(scalability, low impact).
