> Python processors are set to be single threaded as only one embedded python
> interpreter is used, so the global interpreter lock can only be held by one
> processor at a time. Still we could enable multithreading as python
> processors could let go of the GIL in case of sleeping threads, waiting for
> IO, http response etc. We should let the interpreter decide when to let go of
> the GIL, but also give the option to make any custom python processor to be
> single threaded if the developer of the processor decides so. This option
> should be available for both MiNiFi and NiFi style python processors.
