We should not use RUSAGE_SELF on Linux, FreeBSD and other platforms?

This function is called in two contexts -- one when the benchmark runs entirely in a separate subprocess, in which case we want CHILDREN, and one when in which it runs in the same process, where we want SELF. Saying that, it would probably clearer to not have a default value for resource_type here.

resource.RUSAGE_CHILDREN doesn't work on Windows: resource module is not available there.
You should add an abstraction, like having a children=True parameter for get_max_rss().

In c960443, which fixed a bug in scaling the
mem_max_rssvalue on Darwin, I inadvertently changed the measurement from usingRUSAGE_SELFtoRUSAGE_CHILDREN. This has resulted in the measurements being much coarser and incorrect on Darwin. This reverts to the old correct behavior.
