Description:
------------
When a large # of files are opend, written and closed, memory 
is never released. I tested it on windows and linux. Samve 
Problem. Strange thing, when the files are deleted on the 
linux version, the memory is released.

Reproduce code:
---------------
for($i=0;$i<10000;$i++)
{
	$h = fopen('/home/testdir/testfile'.$i.'.html','w');

	fwrite($h,'AAAA');

	fclose($h);


}
