Please note that all os.path functions are *awfully* slow! If ever possible
use a nonportable self made scheme.

It drove me nearly crazy when I detected that os.path split and join
operations took even longer than raw disk access in a directory scan
program....

(The other issue (decorated sorting) is more relevent of course.)
