> 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
