On 2xSMP

Ran tvtime, exited it (seemingly) OK, but shell didn't return. No
reaction to ^C, however ^Z brought shell back. Killed tvtime and bash
reported that it was terminated. Load went to 1. Did a 'ps aux', which
'hanged' after displaying most of process list. So I straced another
one, which hanged at read() of /proc/<pid>/cmdline (<pid> was of
supposedly dead tvtime). Also, these didn't react to ^C nor ^Z.
kill -9 -1 <pidofdeadtvtime> hanged machine solid.

Found that dump in log later. I know it's not Oops, what is it?

This could be an older issue, I had a 2.6.9-mm1 which suddenly put
load to 1 and never went down from that (it did reboot cleanly into
2.6.10-rc1-mm3).
