Multithread in SSEtoRServ

[strelokr]

Description

How to run multithread requests

Steps to Reproduce

example enviroment:
RnD Qlik sense server with SSEtoRServ.exe connected to RServe on Docker.
Developer Qlik sense server connected to WinSRV machine with SSEtoRServ.exe connected to RServe on Docker
Demo Qlik sense server connected to WinSRV machine with SSEtoRServ.exe connected to RServe on Docker
See scheme in attached image.

Expected behavior

Running requests to R from all QS servers in same time in parallel threads

Actual behavior

Demo QS and Developer QS server connected to R using the same SSEtoRServe plugin runing on WinSRV machine.
Requests for calculations are queued and executed in one thread. No mater all requests from Demo server or half from Demo, half from Dev Server - in same time run only one calculation. At the same time during calculations from those servers, the RnD QS server using own copy of the SSEtoRServ plugin can perform calculations using the same RServe without any delay.
How to run parallel calculations within one SSEtoRServe plugin?
