Re: pluto not responding -- possibly not re-entrant (updown)

Yes.  I added a paragraph right after I sent my reply.

       Pluto waits for the script to finish and will not do any other process-
       ing  while  it  is  waiting.  The script may assume that pluto will not
       change anything while the script runs.  The script should  avoid  doing
       anything  that takes much time and it should not issue any command that
       requires processing by pluto.  Either of these activities could be per-
       formed by a background subprocess of the script.

| Also, as mentioned in my previous note, one could
| imagine detecting attempted re-entrancy (perhaps
| based on pgid) and producing an error message
| rather than a hang.

I'm too lazy, at least for now :-)
