Completely different things --- for ACLs, the requirement is that the
update is atomic with respect to other running processes accessing the
data in memory. For transactions, the update is atomic with respect
to the disk state after a crash.
Exporting a transaction API for disk updates would be useful but is
definitely an orthogonal problem.
