Do you do any sort of 'locking of potential names' to ensure that
another process adding a sequence at the same time or something won't
get the same name first, causing yours to still fail or break uniqueness?

Or do we just not care since it's unlikely to happen and our transation
would likely have some exclusive lock anyway?
