You should likely add an entry to powerpc/unittests.cfg ...
also, wouldn't it be better to extend the sprs.elf test for this, so that it 
e.g. changes some stuff for each migration?

It was supposed to be kind of a dumb stress tester for the harness
that just runs as quickly as possible for a long time :) I'll see if
it can be massaged into something more useful.

sprs (and others) probably should get better migration stressing
when multi-migration support lands in the harness, but I was
thinking that could be follow up patches.

Thanks,
