It would be nice to be able to set the priority of the process to start in the run configuration. Especially when doing extensive test calculations, setting a low priority is appreciated in order to be able to use the system properly. With a lower process priority it might as well be a little bit easier to kill a program which got stuck in a deadlock or endless loop. Especially on windows, where you cannot use a script to set the priority, it is very tiring to fire up the process manager for each run. I know this feature is heavily platform dependent, but perhaps there exists a small native helper lib for setting process priority.
