I found some of the data in my GC timings to be a little confusing. I can understand how different runs of the compiler might have different space usages even when compiling the same thing (things like timestamps are going to change), but the variation is too large to explain away like this. I think the problem is that by instrumenting the code to measure the timings I have inadvertently changed the behavior of the code beyond simply collecting the data.
