Reported by zbe...@chromium.org, Aug 12, 2011
This happened today in a chromiumos-sdk builder, see the log:
http://build.chromium.org/p/chromiumos/builders/chromiumos%20sdk/builds/49/steps/cbuildbot/logs/stdio

Printout of parallel_emerge run looks like this:
...
Pending 303, Ready 42, Running 4, Retrying 0, Total 303 [Time 2m14.6s Load 1.7 1.23 0.66]
Traceback (most recent call last):
  File "/home/chrome-bot/trunk/chromite/bin/parallel_emerge", line 1451, in <module>
  File "/home/chrome-bot/trunk/chromite/bin/parallel_emerge", line 1431, in main
  File "/home/chrome-bot/trunk/chromite/bin/parallel_emerge", line 1317, in Run
  File "/home/chrome-bot/trunk/chromite/bin/parallel_emerge", line 1238, in _Status
OSError: Load averages are unobtainable


I'm not sure what could cause that exception, but may be worth to handle it more cleanly, as showing loadavg isn't vital to the operation.

Looks like chroot was unmounted by hand. Here are logs from buildbot:
 - At 12:59pm parallel_emerge started
 - At 1:00pm someone logged in to the buildbot with a password
 - At 1:01pm someone ran enter_chroot.sh or cros_sdk and this unmounted the running chroot.

Might be a bug in enter_chroot. Can you investigate why running enter_chroot would kill the buildbot? enter_chroot is supposed to have locking to prevent this...

Looks like it was in the middle of make_chroot when someone ran enter_chroot. Marking as a duplicate of 19144.
