description: >
Use a 32-bit reference count field.
While on some 64-bit systems it's theoretically possible to wrap a 32-bit
counter field, assuming a 16-byte duk_tval the Duktape heap would have to
be larger than 64GB for that to happen. Because of this the default is to
use a 32-bit refcount field.
