The directory "." will still exist while you have it open (your current
directory), but will be unreachable, as you observed with stat(1) and
the number of links.

Would checking for "test -d $PWD" work?  I think $PWD is the full path
and so if it's no longer reachable, the test should fail?

Hope that helps
