Fun, everytime the process migrate we'll have to change the PID (i assume
this will be generic and cluster with processes migrating will use it)

As far as i know pid is a pid_t that is a int in all the plataforms.


Add a new field in task struct (we'll end adding a new structure there
anyway) 32 bits if you want with the node number.
You can begin with node number 0 and then start the clusteringd that read
that node number from /etc/
