But this one is easy to avoid.  I really don't understand why this bug
has gone on and on.  What's the objection to "/"?  As far as I can tell
it's smaller, faster, and certain to work.  (Faster especially if
there's some nfs or ftpfs or similar involved where a system chdir may
do some evil remote query.)

Sounds good.  Tramp holds open a session doesn't it, so at least there'd
be no call-process to worry about for it. :)
