Actually, the problem is not from my Friday changes.  I pulled the
initrd's from David's machines.  The machine with only 8 failures had
a correct initrd, while the others had an older version that was made
before the init script was made to be +x.  Not sure why.  He is going
to blow away all of his existing trees today and see if that fixes the
problem.

Having the rcS file not +x meant that /proc wasn't being mounted,
which led to many failures.  We cleared this up shortly after the
import since a lot of file permissions were lost.

Current versions run in about half the time of 0.3 on my machine.
Also, the current version of the runtest script has a "quick" mode
that only runs a subset of the whole suite, which exercises some key
areas.  I definitely think that the mini XenRT should be at least
running the latest quick tests.
