I haven't been following this completely, but:

The GC also has a compile-time flag NO_EXECUTE_PERMISSION, which affects heap executability.  I think the documentation says that this only affects incremental collection, but looking at the code, I'm not sure I believe that anymore.  I think it generally affects whether memory allocated with mmap is made executable, and we've been doing more and more of that.
