Delete a very, very deep tree of subdirectories on windows?

I was testing a file management program today and while looking to solve something else my program ended up not checking for moving a directory to the same directory.

The result is a possibly endless recursion of dir1s. I need to commit the changes so I'm desperate to get these out of my repository.

Any ideas?

Basically.. what I got is:

dir/dir/dir/dir........./dir/dir/dir It's probably on the thousands.
