I have seen this both with mm2, m33 and mm4.
Suddenly, the load meter jumps.
Using ps & top, I see one process using 100% cpu.
This is always a process that was exiting, this tend to happen
when I close applications, or doing debian upgrades which
runs lots of short-lived processes.
I believe it is running in the kernel, ps lists it with stat "RN"
and it cannot be killed, not even with kill -9 from root.
Something wrong with process termination?
The machine is still useable, although with less power.
renicing the unkillable cpu hog seems to help. I have not
yet seen more than one process end up like this.
