That's not a very optimal approach for two reaons:
1) it requires a host with MAXPHYS < 64k unnecessarily limiting
   testing of MI code to a handful of setups.  I don't test my MI changes
   on a xen domu, and I assume there are others, the anita runs being
   the most important example.
2) in case the test produces a useful result (i.e. fails), your test
   host will have panicked.
