Hi Tim,

Here's the output:

~# erl
Erlang R15B03 (erts- [source] [64-bit] [smp:8:8] 
[async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9.3.1  (abort with ^G)
BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
        (v)ersion (k)ill (D)b-tables (d)istribution

So that unfortunately confirms that epoll is not enabled. Any hints on 
how to change this? Is it configurable or do we have to compile the 
package ourselves?
