That's very odd. Processes in 'D' = uninterruptible sleep ?
I looked through the entire process list all but 3 were "sleeping", 2
were stopped (I did that in a terminal, a less instance and an
emacsclient instance) and one was zombie (again I know this one, it's
the src-hilite attached to the stopped less instance).
