  2. as part of procmail.

  4. can't create all the specified files (in the specified order), it waits
  5. sleeptime (defaults to 8) seconds and retries the last file that didn't
  6. succeed. You can specify the number of retries to do until failure is
  7. returned. If the number of retries is -1 (default, i.e., -r-1) lockfile
  8. will retry forever.
