Description:
------------
When I use "sleep", to wait until cache "fruit" to be invalidated, the cache still exists and contains the data.

Reproduce code:
---------------
<?php

  apc_clear_cache('user');

  apc_store('fruit', 'grape', 1);

  sleep(3);

  $has = null;
  var_dump(apc_fetch('fruit', $has));

  var_dump($has);

Expected result:
----------------
Script output should be:

NULL
false

Actual result:
--------------
Be running this script i got:

string 'grape' (length=5)
boolean true
