No, that is not right. If it was it would totally defeat the entire 
purpose of snapshots (which *is* to get a consistent view of the

Yes - read up on how snapshots work (in your case ZFS snapshots) and 
stop wasting brain cycles worrying about a non existent problem.

As I said earlier, the only exception to this consistency question is 
with SQL databases.
