it would be nice to be able to set a higher priority on some critical nodes:

For example using the psutil library, which is a cross-platform library for accessing system details and managing processes:

# Set the process priority using psutil
    try:
        ps_process = psutil.Process(self.proc)
        # Set the priority (you can choose a priority value from psutil)
        ps_process.nice(psutil.HIGH_PRIORITY_CLASS)
    except psutil.NoSuchProcess as e:
        log.error(f"Error setting priority: {e}")
