Chris Pearce 1cfc65da51 Bug 1392747 - Backed out changeset 6524c2d721db. r=backout
The logging added in this patch was landed to help debug very rare shutdown
failures on android, but the logging runs on other platforms and is annoying.
No one is looking at fixing the rare shutdown problem on Android. So remove the
logging until fixing the shutdown failure becomes a priority.
