I should have refrained from touching the keyboard so late at night
X-<.  This regression was done long time ago (even in v2.1.0 I see
that ref_transaction_commit() tries to grab all locks at once).

So it is only "push --atomic".

The choice is between (1) shipping "push --atomic" that is known to
be broken, (2) applying your five-patch series which may (a) fix
both "push --atomic" and "update-ref --stdin", or (b) break other
transaction users including "update-ref -stdin" in unexpected ways.

I dunno.  I am still tempted to go route (2) hoping that it would
result in (2-a) not (2-b).
