Comment 36 for bug 574910

IMHO, if the problem is exhibited without the EC2 code, then the EC2 code is just that much less code to interact with while debugging this issue. The act of 'adding it back in' is a distraction (more or less) at this point and effort should be placed on tracking down the high load average issue. Once that is found adding back in EC2 code can be tested in the same QA cycle.
