Based on my experience, (at least for m68k) watchpoint is not easy to
use. This reduced the performance in 1:100 order, and gdb can not
detect properly for the memory access. So I gave up to use watchpoint
on this architecture. I am interested whether it is ok for other
architecture or not.

The 'ecos' port done by Simby has not been merged, and Coldfire port
(or actually, it is Dragonball port, if I remember correctly)
done by Transvirtual has not been merged. So this combination is new
CPU with new OS, much worse than just trying new OS ;-)

BTW, uClinux should be another new OS for Kaffe, based on my understanding,
am I right? (Of course I know uClinux is very very close to the original
linux, but again 'slight' difference introduces many fancy thing to debug)
