  26    If it didn't terminate correctly, exit if exit_on_error is true, otherwise
  27    return 127.
  28    If ignore_sigpipe is true, consider a subprocess termination due to SIGPIPE
  29    as equivalent to a success.  This is suitable for processes whose only
  30    purpose is to write to standard output.
  31    If slave_process is true, the child process will be terminated when its
  32    creator receives a catchable fatal signal.
  33    It is recommended that no signal is blocked or ignored while execute()
  34    is called.  See pipe.h for the reason.  */
