There is a complication on the x86_64 platform, where pointers are

The 2 cases BlockedOnGA and BlockedOnGA_NoSend are needed in a GUM
setup only. They mark a TSO that has entered a FETCH_ME or
FETCH_ME_BQ closure, respectively; only the first TSO hitting the
closure will send a Fetch message.
Currently we have no separate code for blocking on an RBH; we use the
BlockedOnBlackHole case for that. -- HWL
