Calculating the max. clients by worker_connections

[Antoine BONAVITA]

I would say "and nginx uses the fds (file descriptors) from the same pool to 
connect to the upstream backen" (wiki quote). But that should be 2, not 4: I 
agree with you on this.
If any of the gurus out there could shed light on this, I'm sure a lot of us 
would appreciate.

Antoine.
