  I've looked at these a bit, but since they make substantial changes to
some of the code I'm currently working on to get R4000 DECstation support,
I'm reluctant to complicate my work more than it already is.  I would like
to get my R4000 changes working well enough enough to commit to -current
and then try to get these new changes merged.  I may add the minidebugger
though, since it may help when debugging the R4000 changes.  Eliminating
the double-mapped kernel stack would make the R4000 support easier, since
some of my problems have been related to this.
