Thanks for the questions!

The loop that is taking all the time is mostly cpu intensive with a decent memory footprint (but no where near my laptop limits)
Its runs a large loop of loops performing string compares, index functions and regex on each element.

I am reasonably sure that the test code is deterministic.
There is some usage of the keys function to order the way we go through the loop,
but on hashes with very few keys and the order of the keys really don't affect anything.

I think my data-point about the effect of opening gmail on a freshely rebooted laptop is the most revealing item.
I've been playing with my power profile, but It doesn't seem to be doing any good... the fan goes up and down throughout the longer tests.
