Hi Thierry,

     there's an unadvertised primitive called Context>>#xRay (or ContextPart>>#xRay) that answers these questions for tests.  I'm away from the system right now but I'll get you the source soon.  Also, the limit on jutting methods, 60 literals, is a default. There's a command line option -maxcoglits (IIRC) that you can change.
