I let it run for a 3 or 4 days, but it found no more passwords. I gave 
up on it. as I had 14 threads.
Before I rebooted, it was finding passwords at an acceptable rate.
Not having a checkpoint for 3*14 days of work seems like a bug to me.
i decided to start from scratch with a different dictionary, in a 
different directory in case there was anything to debug with the issue.
