> Accord has a AbstractConfigurationService that locks on “this” and does this
> over large ares, even when the lock is not needed. This has been found to
> cause issues as messaging gets blocked on this causing timeouts.
> To better improve things, we should lower the locking to what is needed and
> avoid locking while triggering callbacks
