Severity: important

--- 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
