> There seems to be a Connection<->Processor shared_ptr cycle which means that
> the Processors never get destructed.
> This causes leaks in reloads and in tests.
> There are also other cycles causing leaks:
> * Connection <-> FlowFile (this seems to be partially mitigated by
> Connection::drain(), but not entirely)
> * ResourceClaim <-> VolatileContentRepository
> * VolatileContentRepository <-> VolatileContentRepository (capturing a
> shared_ptr into a thread func and detaching the thread)
> * FlowController <- > SchedulingAgent (TimerDrivenSchedulingAgent,
> EventDrivenSchedulingAgent, CronDrivenSchedulingAgent) and even
> FlowController <- > util::ThreadPool because of this
