We have historically turned of various NRWT behaviors on a bot-by-bot basis if necessary. It's possible these machines just need more RAM as Adam mentioned, and we should keep parallel testing on mac, but disable just these machines. I'm open to either option of course: http://trac.webkit.org/browser/trunk/Tools/Scripts/run-webkit-tests#L49
