Bug description:  Memory leak in XSLTProcessor->transformToDoc()

Description:
------------
Using a certain data the function call to XSLTProcessor->transformToDoc()
produces a 2kb-4kb memory leak. This happens *only* on win32 (tested on NT
5.0 build 2195 and
NT 5.2 build 3790) platform. Reproduced succesfully on apache 2.0.55 and
2.0.59 with php 5.1.6 and todays snapshot 5.2.0RC6-dev.

Reproduce code:
---------------
Code is standard (taken from manual) procedure to transform XML+XSTL into
a HTML document. Both URLs contain same files:
1.xml - source XML data
1.xsl - source XSLT data
character-entities.dtd - necessery entities definitions 
test.txt - PHP source code for the transformation

URL1: (not online 24/7, showing the current php process usage on server)
https://81.27.200.150:13580/transformToDoc/test.php

URL2: (online 24/7, not showing the current mem usage - for downloading
only) http://virklis.cust.ignum.cz/transformToDoc/test.php


Actual result:
--------------
Every page refresh produces a 2-4Kb raise in memory used by PHP (see live
on https://81.27.200.150:13580/transformToDoc/test.php)
