There is a problem with the 'async' option for the system command.

for ii = 1:1000
  system ('ls', false, 'async');
end


The code above causes 1000 zombie processes to hang around after they finish.
They are called "<defunct>" in ps or htop. They only disappear when Octave
itself is exited.

The code below makes them finish properly and not hang around:

for ii = 1:1000
  system ('ls &');
end
