Note that use of transactional processing is inherently dual path.
You would still need the "other" path even if every machine in the world
already supported TBEGIN.
Why?
A non-constrained transaction needs a fallback path to deal with
anything other than CC=0 from TBEGIN. If you get CC=1 or CC=3 you really
have no choice but to go to the fallback path. You could retry after
CC=2, but you don't want to get into a loop doing so. So you really need
to set a single-digit retry limit and go to the fallback path when it's
reached.
