  # doesn't work under Cygwin; its kill command doesn't recognize
  # the PID of the real background process, but it does work on the
  # PID of the helper process.  So we save the value of $! in the
  # SHELL_HTTPPID variable, and use it instead of the ${HTTPPID}
  # file under Cygwin.  (In fact, this should work in any shell
