actually you are going to go nuts tracking all those variables,
e.g. what if I do in a shell window,
$ cd
$ su bob
$ cd inside
etc. while you are tracking $PWD unless you somehow have a behind the
scenes connection to get the real scoop from /proc or bash itself...
Oh, and say bob's dir is mode 700
$ su -c 'echo are you still following me?; bash -i' jimmy
$ cd; echo i said su _-c_ to keep you off the trail, but then used bash -i

Anyway, it will never track perfectly.
