Comment (by Alexandre Oliva):

 The problem, much as I can tell, is that unlink "moves" the readdir
 "offset", so that b gets skipped in the unlinking loop.  It shouldn't be
 skipped, and the loop should unlink every entry, leaving the directory
 empty.  The bug is that it doesn't, and every other entry survives because
 unlinking causes it to be skipped.
