Comment (by ksandarusi):

 I'd like to take on this but if someone could make sure I am headed in the
 right direction it would be much appreciated.

 After combing through the steps code for buildbot, it looks as if the
 trickiest part is creating a multi-platform solution. My first thought is
 to simply execute a one-line python command on the shell. A quick test and
 this following command works:[[BR]]
 {{{
 python -c "import multiprocessing; print multiprocessing.cpu_count()"
 }}}[[BR]]
 All that would be required is a pass of this command and a receive of its
 output. Once received, a property would simply be set.
