0.92 Thu Apr 18 15:02:03 2019
    - thanks to xantronix for both all of these features (and some nice fixups to the tests):
        - add support for persistent PID files; allow traversing /proc/$pid/fd
          to ensure a process indicated by a PID file still holds an open file
          descriptor for that PID file
        - add support for checking a PID file's minimum mtime value when testing
          if the PID file indicates a running PID
