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

Generally you never do a store and a fetch from within the 
same request.  It makes very little sense to do so since you 
have the data you stored already.  In order to save a system 
call, apc_fetch() call uses the request time which is set at 
the start of the request to check the ttl of the entry.  If 
you really want to store and fetch from within the same 
request set:

apc.use_request_time = 0
