I think we discussed that, shortly at least?  Hmm, maybe my
memory failing.  Thats likely :-P

Callbacks have a simple mechanism to ensure they get only
called once: if they return 'False' they get removed from
the metric.  Copying callbacks would void that policy, and
would require the application to track callback instances
carefully.  

Error conditions: The motivation was to start a new object
instance with a clean record.  

I'll add some words in that sense.

The consistency model holds for all operations.  Yes, we
should quote the POSIX spec - however, I could not find an
explicit description of the consistency model, yet.  Can
anybody help?

Cheers, Andre.
