> This bug was discovered when using the same avro schema object to decode many
> messages in parallel.
> A reference count used to manage the some pointers used by the schema was not
> atomic, so race conditions caused them to be decremented more than they were
> incremented (and thus, deleted).
> The solution is to use atomic counters for references, and by switching to
> boost::shared_ptr, we get this.
