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.

Title:
  Manage Scheduling Priority of PTBatcherGUI

  I don't now if this exists in Windows.  In Linux (and I guess also on
  the Mac), I can start a command with `nice -n X COMMAND ARGS` and it
  has higher or lower scheduling priority depending if X is negative or
  positive.  Details in `man nice`.

  I guess I could pre-pend the nice command in the call from
  PanoPanel.cpp but I am not sure how this would (or would not) affect
  the whole thing.
