If I understand it right, as long as the "counter" is used
within a single thread and not across threads there shouldn't
be any issues. Same as a cache.
If the idea is to use one counter across multiple threads
then refs can be used.
I don't think I follow why mk-counter would be retried. There
is not reason for it to fail as it simply creates a new "counter"
and returns it and doesn't need to block or be blocked.
