As I am not sure if the Erlang version in these distributions already have the
epoll patch of the Gizmo Project people
( http://www.gizmoproject.com/ )included, it might be better to choose
FreeBSD then. This because the FreeBSD ports of ejabberd and Erlang support
kernel polling for sure.

Hint: a Round-robin howto is still missing in both the guide and the website
