I noticed that the i860 has this feature on-chip.  I don't know if it
is available with the CMMU's for other current 32-bit micros (e.g. 88k,
MIPS, SPARC).  If anyone else knows, please tell me.

Now if we could just get support for such things via standard UNIX ptrace
calls, and then get the GNU Debugger (gdb) to actually bring such facilities
out to the user's level...
