Details

In Bug 1545582 js/src/vm/Runtime.cpp the allocation sampling probability is hard coded to 0.1. We should hook it up as a configurable parameter of some kind. DMD has two different modes, either some smaller probability, or a probability of 100% to record every allocation. We should consider what type of probability we want to put here and how to configure it.
