 The `BIND10_COMPONENT_FAILED component %1 (pid %2) failed with %3 exit
 status` log message is not too helpful (as can be seen in #1672, for
 example), as it produces the exit status in raw, undecoded format. We
 might want to use some of these functions to decode it and provide some
 reasonable output:
  * `os.WCOREDUMP()`
  * `os.WIFCONTINUED()`
  * `os.WIFSTOPPED()`
  * `os.WIFSIGNALED()`
  * `os.WIFEXITED()`
  * `os.WSTOPSIG()`
