Expired cache stores weak references. I.e. while the program is
holding a (non-weak) reference to a row the cache will return the same
row. The moment you free the last reference to the row the expired cache
is cleared and next time you will get a new row.
Get rid of f before getting f1:
del f
or
f = None
will do.
