Queue RushTI Executions #71
Description
Introduce an alternative run mode that avoids overlapping RushTI executions.
So when RushTI is called to run with n threads by two separate callers at approximately the same time, execution two should queue and only start after execution one is completed.
This avoids the situation that n*2 threads are running in TM1 and potentially overwhelm the TM1 server.
