SIGUSR1 and SIGUSR2 are signals that can be used by any application and 
have application-defined-meaning. I've added them to make 
disconnect-on-suspend available for users how can't use other signal for 
any reason. This signal is never emitted by system! In fact linux don't 
send any of the signals (AFAIK), they are used by unix or BSD, but can 
be sent by userspace script called hibernate, which suspends the 
machine. I've no idea if suspend2 developers would like to change the 
factory version of hibernate script, I can't get answer from them. I've 
simply heard from users that it's needed feature (I've the same 
feeling), so it makes disconnect-on-hibernate possible for them.
I'm not sure if this version is the one you should apply to official Psi 
but I know some users would use this patch.
