You're modifying subdir *while* you're iterating over it.  You can read the
full story on why you shouldn't do that in the Language Reference Manual
(see the section about "for" loops).  Try

    for thing in subdir[:]:

instead.  That is, iterate over a *copy* of subdir.  Then modifications to
the original won't interfere with the iteration (which is over a copy).
