Welcome to Windows.  If Windows can't delete a directory while it is the
current directory of some process then there is no way that Cygwin can
do this either.

The Single Unix Specification does seem to imply that deleting the current
working directory should succeed but there are some UNIX systems out there
that don't adhere to this.  For instance, I just tried this on IRIX 5.3
and it failed to rmdir a directory if I was cd'ed to it.
