I don't have a strong opinion, but the idea looks good and I can see
the need for it.  Also, this is possibly specifically because we
designed log messages to be identifiable, if this is based on real
user need that would be a nice appealing functionality unique to BIND
10.

My comment at this point is that we should be careful about its
performance impact.  If we use std::map and when it's empty (and it
should be the normal case) as you hinted, that's probably lightweight,
but I think we need to measure its impact via real benchmark tests.
We should also make sure that specifying a filter (disable/enable a
particular message) doesn't so significantly damage the peformance.

I also see the point in Stephen's response.  While I can imagine a
user that will be happy with this feature, it would be nice if we
could know how widely it would be needed.
