With 2k connections the overhead of select() is going to start to be a problem. You would notice the system time going up. -threaded may help with this, because it calls select() less often.

we should be using /dev/poll on systems that support it. it cuts down on the overhead a whole lot. 'poll(2)' is also mostly portable and usually better than select since there is no arbitrary file descriptor limit and it doesn't have to traverse the whole bitset. a few #ifdefs should let us choose the optimum one available on any given system.
