[SAC] Fair projectsVM usage (esp. Openlayers)

[Markus Neteler]

I would like to remind folks to set cron jobs "nice"ly, otherwise
the performance goes down (read: unresponsive):


top - 00:21:37 up 10 days,  3:53,  1 user,  load average: 42.23,

See the load average.

Solution: Put the word "nice" in front of your jobs to run them with nice
level 10 rather than 0.

Yes, please do recheck your jobs. Thanks.
