Thanks. Very nice.
I have two comments but I think they are very minor details I
can and should fix in my inbox and apply, instead of asking you
to update and resend.

The original I did was sloppy and did not detect this situation;
thanks for fixing it. You do not refuse the primary operation,
which is to update the ref, so this should be a warning instead
of an error, I think.

This removal makes "struct ref_lock *lock" (not shown in the
context) unused. I will remove the declaration.
