Our Buildbot/Katana instance quite frequently runs at 100% CPU utilization
during busy times. This (probably) creates problems with scheduling of new
builds and makes the UI sluggish. It also make it problematic for us to add
increase number of slaves and add new builders.

The reason we want to try running it under pypy is two fold. First we hope
it will lower the CPU load and give us some breathing space short term.
Also we hope to be able to run vmprof profiler to collect data, so that we
can figure out where buildbot is spending it's time. Which will gives us
better idea on how to address performance problems.
