Agreed.

I merged the contribution mostly as-is because I don't have an android
build environment set up. (I need to reinstall a system to get an
environment to set up AOSP in, and the release deadline was 4 days
overdue...)

My target is making these guys happy:

https://code.google.com/p/android/issues/detail?id=76861

That said, I see they posted their own diff to that thread since the
last time I looked at it, so I'll see about merging that instead.

Isaac Dunham did the patch I merged. I have some local logistical issues
freeing up a machine with enough resources to build AOSP, they're all
doing things I need them to do yet bad for AOSP in one way or another, I
need to devote a weekend to reinstalling one...

I'll try to get the better android patch applied this weekend. (The
annotation of individual commands that won't work without utmpx and such
in the old patch is good, so I should merge the two...)

Thank you,

Rob
