and static data, and registers.  (I have a plan to scan data precisely as
well.  The latter is a bit harder.)

Highly unlikely.  Conservative GC seems a good fit for libgcj, which is
really quite simple throughout (ignoring the compiler).

But these are choices based on design principles.  For instance, Boehm's
collector wouldn't have been a good fit for SableVM with your portability
constraints.
