Pbbuttonsd installs an message queue which it can't clean up if kicked off 
with kill -9. Use 'ipcs' (as root) to check the message queue id and after 
that remove it with 'ipcrm msg <msgid>'. After that procedure pbbuttonsd will 
start again without reboot.

It seems that the new problems occour in conjunction with kernel 2.6.7. Most 
of you use it. I never saw those problems with kernel 2.4, so I have to 
install kernel 2.6.7 and have a closer look. 

There have been a lot of changes since pbbuttons 0.5.9 but the sleep code 
didn't change, so I have no explanation for the failures yet. I'm thankful 
for every hint how this behaviour can be deterministically reproduced.
