AppDomain as a sandbox and stack overflow

Hi

One of the issues which AppDomains are facing is problem of unsecure
code execution in a sandbox. One of its aspects are unhandled
exceptions thrown inside domains - they should not destabilize rest of
the application. And, it is truly possible to do that, however I can't
see any way to prevent from crashing the application when a stack
overflow exception appears inside a domain which is supposed to serve
as a sandbox.

This happens when a new thread is launched in the domain, and it
causes a stack overflow exception. Depending on .net framework
version, the behavior slightly differs, but anyway I can't see any way
of handling such event gently.

Do you know, how to prevent AppDomains from crashing the application?
Is it possible to apply some dedicated security restriction, or sth?
Otherwise, AppDomains can't be regarded as real sandboxes.
