If the contents of f are larger than memory, this won't work.  If the
contents of f are large compared to memory, then it won't work very well.

This is one reason that 2.1 will include "xreadlines", which will work
just like the above:
        for z in f.xreadlines():
                print z
but will never hold the entire file in memory.
