Chaskiel set me straight:
        sphinx /tmp  > rmdir testdir
        shell1:
        sphinx /tmp/testdir  > ls -l /proc/$$/cwd
        lrwxrwxrwx    1 cg2v     staff           0 Jul 27 19:09 /proc/4523/cwd -> /tmp/testdir (deleted)

I've never seen this before, but I probably haven't looked. I'd have to 
look at the linux kernel's handling before I understand why.
