 It would be nice if we could find a work around, especially for XML.

 I just tried this from an IHttpHandler, and it freezes just the same.
 So this is *not* aspx, but System.Web.

+After a mammoth debugging session with nothing but trusty olf
+WriteLine at my
+side I have some final and useful info on why the file reads are
+failing. In
+FileWebRequest.cs inside the method:
+public override IAsyncResult BeginGetResponse (AsyncCallback callback,
+there is a statement that is meant to be executed asynchronously with
+the rest
+of the code. i.e.
+return c.BeginInvoke (callback, state);
+This should run the GetResponseInternal () function asynchronously and
+an IAsyncResult to sync with. It is this function that is attempting
+to read
+the file. Sadly, the thread doesn't seem to launch (or whatever is
+meant to
+happen), the function doesn't start to execute until *after* the
+timeout has
+occurred, and so the file is never returned.
+Hopefully someone familiar with the insides of Mono can cast some
+light and
+bug fixes on this one ;->
