mmap on Mac M1 is super slow!

[hbrodin]

Create a tiny program

int main() { return 0; }

If instrumented with polytracker it still takes a long time to run (15 secs?) If I run

strace ./a.out

I can see that the mmap with the huge size (mmap_taint_forest) takes all the time. This is not the case when running on the X86 Mac.
