Description:
------------
Seeing some unexpected behavior when getting a mysql "result set not freed" warning while using zlib.output_compression + mysql.trace_mode - the warning is not displayed, and getting some intermittent reload behavior in IE6 if the page also has a large amount of content

Reproduce code:
---------------
<?php
// php.ini or other valid ini locations:
// zlib.output_compression on
// mysql.trace_mode on

// nothing wrong with this - just sets up the scenario
mysql_connect("valid_host", "valid_username", "valid_password");
mysql_select_db("valid_db");

// large amount of content - enables intermittent IE6 reload behavior
for ($x=1; $x<=250000; $x++) {echo htmlentities(chr(rand(32, 126)));}

// trigger "result set not freed" warning
// assume valid_table has at least two records
$query=mysql_query("select valid_field from valid_table limit 2");
list($value)=mysql_fetch_row($query);
?>

Expected result:
----------------
250000 random ASCII characters followed by:

Warning: Unknown: 1 result set(s) not freed. Use mysql_free_result to free result sets which were requested using mysql_query() in Unknown on line 0


Actual result:
--------------
Firefox: 250000 random ASCII characters, no warning
IE6: same, plus intermittent reload behavior
