I've been experimenting with profiled bootstraps using sample profiles. Initially, I made stage2 build stage3 while running under Perf. This produced a 20Gb profile which took too long to convert to LLVM, and used ~30Gb of RAM. So, I decided that this was not going to be very useful for general usage. I then changed the bootstrap to instead run each individual compile under Perf. This
