[Openais] rrp test

[Fabien THOMAS]

I've done some test of the ring redundancy code under FreeBSD with  
the following configuration:

3 FreeBSD node with two ring (2 NIC per ring)

It works fine except for:

1) openais-cfgtool completly lock the station until aisexec is  
exited: removing process priority correct the issue but i dont known  
why during the socket close the process
is locked.

2) hole (around 5s) before ring failure detection: it seems that  
during a fault before the ring is declared faultly all communication  
on the other rings is disabled.
Is it a known issue ?

Regards,
Fabien
