That's a legitimate point.

But my point is that whatever behavior we choose here, I want the
commands that operate on a single thread (+, -, a) to operate exactly
the same as the command that operates on all threads (*). Having these
behave subtly different, (as in the current patch) is going to lead to
confusion on the part of the user.

So, tagging only matching messages could make a lot of sense. If so,
let's make the operations on single threads work the same.

The race-condition issues apply to both operations, so I won't make the
current patch block on resolving those.
