In my asp.net IHttpHandler I have set

           context.Response.ContentType = "text/plain";

Which it is clearly returning. In IE8 I get to see this:

When I try the Save Target As... I get this (Notice the Save as type:):

IE is kind of notorious for second-guessing the content type. Presumably they're doing content-sniffing and the <?xml version="1.0"?> is tripping it up.

Try using a different content type other than text/plain or application/octet-stream to see if you get the same behavior. It's looks like it only does the sniffing for those two types in an attempt to work around misconfigured web servers:

It's looking at your actual content which has xml in it:

<?xml version="1.0"?>

It's easy to understand why when you don't have any html elements such as html, head, or body. If you want the xml to be displayed as text then you will need to include in html and escape the markup properly.
