I think I know what needs to be done. From `man erl`:

+K true | false:
Enables  or  disables  the kernel poll functionality if the emulator 
supports it. Default is false (disabled). If the emulator does not 
support kernel poll, and the +K flag is passed to the emulator, a 
warning is issued at startup.

So it's a question of seeing how erlang is started when rabbitmq-server 
is initiated.

Will post back if I come up with a solution.
