I don't really know what exactly would have to be done.
For all I know there is some Win32 API you could use here.
Occasionally we've discussed being able to find the backtraces using
information that is already around, for instance exception-handling
info. We need a more powerful approach because we need to be able to
find the classes whose methods are on the stack; this is used by some
of the Java security features we don't implement.
