One way to deal with the 'rm' is to use 'mark_for_deletion'
from octave-forge. Then the file will be deleted when octave
quits or the next purge_tmp_files.

  bmpwrite(M,hot,'/tmp/junk.bmp');
  mark_for_deletion('/tmp/junk.bmp');
  system('open /tmp/junk.bmp;');

This helps to avoid this kind of race condition.
