The main difference is that GUSS will support several targets, not just
x86 (Pentium) -- and it will have many profiling facilities and complex 
break-
and watchpoints (conditional break/watch:es using guile-scripts).  For 
example,
to my knowledge, Bochs does not gather branch statistics.

Yeah, it is cool.  I wonder how bit-rotten the code is.  I guess that
code for GNUmach has not changed that much (not as much as the Hurd 
code anyway)

The reason for that is that the code is not yet commited to CVS 
repository,
and I do not want people fetching the code from the repository and then 
complaining
about missing features :)
