Seems like this does bad things to iOS PLT. Possibly due to CodeCache vending executables for functions, not unlinkedcodeblocks. So this code might be nuking the unlinked code for those, assuming that Heap tracks CodeCache executables. Need to look into it.
Also this was a much smaller win on bots than throwing away linked code was.
