Comment (by jstressman):
OK... after doing some "git bisect" investigating, and double checking
with extra clean checkouts, we've narrowed down the introduction of the
boot problem to Pawel's scheduler changes in hrev46690

I have no idea how this has led to the /etc/shadow error, but it appears
to be the problematic revision.
On top of this bug, I noticed another bug that I've filed another ticket
for (#11685);
The CPU up through hrev46689 would idle between 0 and 2%... almost
flatline... but starting with hrev46690, it will spike every few seconds
for anywhere from half a second to a few seconds during which the system
basically freezes. This makes the system almost unusable for getting any
work done.
I'll attach screenshots of ActivityMonitor on a fresh boot of hrev46689
and the latest nightly hrev48579 (which behaves the same as hrev46690).
These are both just sitting totally idle with nothing else running.
