Description:
------------
I would aspect to see TCP connection between the apache and the Oracle server to die, after 10seconds the script ends. What i see, is that the connections stays ESTABLISHED until i restart apache.

//php.ini changes
oci8.max_persistent = 2

oci8.persistent_timeout = 10

oci8.ping_interval = -1

Test script:
---------------
  $sql = "SELECT nome FROM f_pessoa";
  $conn = oci_pconnect($user_oracle, $password_db_oracle, $database_oracle);
  $stid = oci_parse($conn, $sql);
  $r = oci_execute($stid, OCI_DEFAULT);
  if (!$r) {
    $e = oci_error($stid);
    echo htmlentities($e['message']);
    exit;
  }
  while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {
    foreach ($row as $item) {
	$table_2 .= ($item?htmlentities($item):' ');
    }
  }
  oci_close($conn);
  oci_free_statement($stid);


Expected result:
----------------
I would expect that TCP connections will die 10s after the script ends.

Actual result:
--------------
The TCP connection between the apache and the Oracle Server stays ESTABLISHED for ever...
