This does not help me.

Short test on windows: change priority of ptbatchergui to high, but started child processes (make/cpfind/nona) are all running with normal priority. So at least on windows changing the process priority of ptbatchergui would not help so much. (Nice does only change the cpu priority, but maybe also the i/o priority needs to be changed.)

 wxExecute - which is used to start make - does not support a priority switch.
