LGTM with the note....


Can you add a unit test for the new option to RunCommand?

Better yet.... is there a plan to replace RunCommand with something that has a
cleaner interface?

Added unittest.  Pushing.

Also ... for RunCommand ... if you can suggest an interface, we can make it
happen :)

This broke the build because I needed to change the test root (now I
assume I'm giving a full path from outside the chroot) in cbuildbot.
I reverted this and will send you a CL for cbuildbot and recommit this
after.

I'd read that code, but never saw the bug until your change.
