[SAC] Fair projectsVM usage (esp. Openlayers)

[Hamish]

can we /please/ "nice ionice -c3" the backula job?  This is ridiculous, the
projects VM turns to mollasses for 20-25 minutes each day as all the apache
processes are deadlocked waiting for access to the disks and respawning
themselves like mad trying to keep availability intact.

currently:
 load average: 103.93, 39.21, 15.08
 Cpu(s):  3.4%us,  2.8%sy,  0.0%ni,  0.0%id, 93.6%wa,  0.0%hi,  0.2%si,  0.0%st


thanks,
Hamish
