I've found where a memory leak in mono 2.0.

It appears on mono 1.9.1, 2.0 (i don't know if it happens on svn) but it
doesn't appears in mono 1.2.6

Test Case : try this page 

<%@ Page Language="C#" Inherits="TestExecute.Default" %>

public class Default : Page
        {

                protected override void OnLoad(System.EventArgs e)
                {
                        Response.Clear();
                        Response.WriteFile("/tmp/test.pdf");

                }
        }

Where /tmp/test.pdf is a >300kB  file

run xsp and do request 
for example :
 /usr/sbin/ab2 -c1 -n 10000  http://localhost:8080/

you'll see the memory growing and growing

I think this bug is the main cause of the out of memory crash on our CMS
