I make a round-robin of connections that I may accept,
Say, of 1 or 5 thousands connections 

once one is valid I forget about the rest , since I only expect one


I guess I am realizing now that for me I have one singular point ,where the certificates are exchanged and verified, when I know the connection is valid.

Maybe your problem is different

I kindof pulled of nowhere the # of 1 to 5 thousand listening threads, as I actually haven't implemented that part on my project yet :p
(and I should, because now I have to wait until the rogue server tires for my thing to kick-in :))

But looking at my system, it says that:

>sysctl -a
...
kern.posix_threads = 200112

so it seems honnest.  You will only use all of the threads against a pack of rogue servers ;)
