Ok, thanks.

The reason is that this is touching a central part of Erlang dogma:
all synchronization is by communication; the only part that needs
locking & friends at all is the run-time, but that one has ot be
correct.

So they're opting to make this new code user-(well, admin) selectable.
We really should move it to an pkg option, and offer it depending on
machine/os; but I won't do *that* at freeze time. Too much code.
