Yes, good point.  I've definitly got that in the back of my mind as
possible ``further work'' :-)  JimB among others remind me of the same
thing.

I think the main thing to decide at this point is, does the change I
proposing in any way preclude this ``further work''?  From your e-mail I
gather that you don't see any problems :-)

The reason I'm trying to keep my proposal separate from idea's such as
yours is that I'd like to see it finished.  Hopefully someone else will,
independantly take on your proposal.

At a more wishy/washy level.  Have you considered viewing GDB as:

	gdb
	  \
	 context - java
	    \
	    frame
	      \
	     target
	        \
	        gdb - hardware
	          \
	          ....

That is, a target that allows the debugging of the JVM might be
implemented using an GDB instance that understands how to access the raw
data.

Again, I don't think my proposed change precludes this model.
