rmdir() failing on directory not empty

[mikeschinkel]

I'm trying to use psysh which uses 0.1 of this library and each time I run it I get:

PHP Warning:  rmdir(/var/folders/.../T/php-xdg-runtime-dir-fallback-mschinkel): Directory not empty in phar:///usr/local/bin/psysh/build-vendor/dnoegel/php-xdg-base-dir/src/Xdg.php on line 110

Looking at your code on line 110 it seems you are doing an rmdir() on a directory containing files.

Maybe you could replace with this from StackOverflow?
