I suspected that the started child processes were all running with normal 
priority.  Managing scheduling priority is a wish.  Maybe it needs to be 
implemented at the make level and not at the PTBatcherGUI level.

Ideally I would like a system that gives priority to the user's interaction 
with the GUI, rather than treating all processes equal and making the user 
wait.

Title:
  Manage Scheduling Priority of PTBatcherGUI

Status in Hugin - Panorama Tools GUI:

  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.
