./configure --enable-threads --enable-smp-support --enable-kernel-poll
checking for working poll()... broken or based on select()
checking whether kqueue() fd can be select()ed on... yes
checking whether kernel poll support should be enabled... yes; kqueue
It should be using kqueue and the Erlang prompt reports that it's
using kqueue. In fact, I distinctly remember being able to go to at
least 20k connections (descriptors) when banging on OpenPoker last year.
It puzzles me greatly that I cannot do better than 1024 this time
Any suggestions on how to troubleshoot?
