Hi,
the machine is a PC (amd64), not virtual. All I said before was regarding SSH sessions only, but right now I happen to be at the site, so I'm able to do some further testing. The following holds:

sleep on SSH, kill on SSH: not working
sleep on SSH, kill on getty: not working
sleep on getty, kill on SSH: working
sleep on getty, kill on getty: working

So this is somewhat SSH related, and I even more suspect a relation to bug #407428. However, the mentioned bug is gone after the last update+reboot, but this one is NOT.

Here is your /proc/status from a sleep running at SSH:

# cat /proc/4781/status
