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

Package: boinc-client
Version: 5.10.30-2
Severity: important
Tags: patch

--- Please enter the report below this line. ---
The CFS in Linux 2.6.24 has the side effect that the boinc user's idle process 
takes about half of the cpu cycles.
This causes severe performance regressions when running boinc-client: half of 
the cpu cycles are always assigned to boinc and the cpu stepping does not get 
increased (from 1GHz to 1.8GHz here), when there is non-boinc load.

The attached patch changes the cpu_share of the boinc user to "2" in the init 
script ("1" would be better probably, but that causes my system to hard-lock, 
others cannot confirm though, see 
http://bugzilla.kernel.org/show_bug.cgi?id=9779).
