After seeing first hand how useful allocation profiling events are in production, but also how extremely expensive they are, we really need to introduce a less costly sampling heap allocation event. One that gives a statistically accurate picture of how much memory is allocated along with the stack traces, but that has a more configurable emission rate. For certain high allocation loads, the recordings can get quite large and they can also introduce quite a bit of overhead.
