In two articles, people have written things like:

+ No, that is not true; the shell exits after TMOUT seconds of idle time
+ (+60 sec grace), and the trap is taken correctly when it exits.

I had the problem with an old Korn Shell (before ksh-i) running under 4.3BSD
on a VAX 780.  It's been too long ago to remember.  But I think the shell
would either hang and not log out or give some error message without doing
the commands in the trap.  Sorry -- I can't remember more than that, and
I have ksh-i now.
