Thanks Mateusz, but still nice level is 0.
I feel that it should be more "friendly" to the other users (and it does not
matter of buildbot takes a few minutes more).

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
25762 buildbot  23   0     0    0    0 R  4.3  0.0   0:00.13 cc1

13360 neteler   16   0  4760 1620 1212 R  0.3  0.2   0:00.26 top

NI = 0 - it would suffice to add "nice" to the launch command.

thanks
