This is just another effect the problem already mentioned: The processes 
does not communicate cracked hashes to the others. I would love to see a 
fix but I'm not likely to pull it through myself. BTW I don't consider 
the fullmpi patch "just mine" so if someone is willing to enhance it, do 
not hesitate to upload a fullmpi-4 or fullmpi-x patch, or start a new 
"branch" depending on how much was changed and/or what you prefer.
