[users at bb.net] buildbot CPU usage

[Vasily]

I'm again suggesting to look into Python profiling capabilities of Intel®
VTune™ Amplifier. It could run statistical profiling for a long time and
display CPU usage over time, so the developer can look at specific time
range where CPU usage was too high and see which functions were executed.

Thanks,
Vasily
