This does not work if the GC updates the pointer concurrently.

The GC will not update a pointer once it is converted to the type uintptr. It becomes invisible to the precise collector, so the uintptr acts as an id value.

Worse, it might be collected then as the collector might think it is no longer in use.

But it's in the map, so it's in use.
