Can you make a bug report with example code and the valgrind
report? I
can take a look at that.

The Zend resource handler is used extensively by things like
the PHP
mysql extension, and I've seen no memory problems even
though I've
used that quite a lot.

No I can not, but:

<?php

for ($i = 0 ; $i > 500; $i++) {
	$qb = new midgardquerybuilder("classname");
        $qb->add_constraint("id",
"=", 1);
	$qb->execute();
}
?>

VS:

<?php
for ($i = 0 ; $i > 500; $i++) {
	$object = new midgard_classname();
	$object->get_by_id(1);
}

Both codes uses the same core's functionality , both uses
zend's hash API.
The first one produces memleak which is proportional to $i.

I do not have php compiled from sources here , so all I (
and valgrind ) can say is '??????'

I doubt you have more than 10 mysql's connection handlers (
with resource handler ) 
available during request. And I am sure that there are much
more than 10 resource handlers 
for QB during request.
