This does not fix the underlying issue that can occur here which is a collision of build_ids.lo between modules in IR decompression. Fixing that requires a somewhat significant overhaul to the serialization of IR (probably using the module identity as a key). This does mean we use a lot more of the bits available here so it makes collisions a lot less likely( they were already extremely rare) but hrtime does tend to only use the lower bits of a 64 bit integer and this will hopefully add some more randomness and make this even less likely
