Well, yes, the group_leader of all the process on the slave must be a 
process on the first node, i guess; but how can i change this: which pid 
should be the new group_leader on the slave node ?

I would be simpler to have an option to slave:start to choose the behavior 
of I/O on slave nodes, imho.
