In which case, the documentation for iglob() is broken.  It says:

"Return an iterator which yields the same values as glob() without 
actually storing them all simultaneously."

If it's calling something which does store them all simultaneously, 
that's like contracting with somebody to commit a crime, and then trying 
to claim you're innocent because you didn't commit the crime yourself.
