Bug#461630: Adjust cpu_share for boinc user (for 2.6.24 cfs scheduler)

[David Herbert]

I've been affected by this bug. I'm using etch with a backport of boinc 
5.10.44-1 and a custom 2.6.24 kernel. It seems that 
the /usr/share/boinc-client/udev-cpu_share script is not getting run or not 
working on my system, /etc/init.d/boinc-client status reports cpu_share: 1024

I tried sudo sh -c 'echo 2 > /sys/kernel/uids/111/cpu_share'
and that worked, status now reports cpu_share: 2
and the sluggishness is gone, until the next reboot.

Now I'm a bit lost tracking down what's wrong.
Any help greatly appreciated.
David.
