#  It obviously takes a bunch of extra time & disk-space to duplicate
#  all of /var/log and then make both a "oldorder" run on the original
#  and a "neworder" run on the copy.  Also, if you do both runs, then
#  the test run will be re-signaling processes which do not need to
#  get signalled (because they are not writing to the copy of the log
#  files that it will be rotating).  If you do not want that extra
#  overhead, just do a regular run here, or maybe exit here and have
#  some other process do the real rotation.
