commit 89b46652c7166317ece0d0f46d64b7c7b793c656 Author: Bernard Ogden bernie.ogden@linaro.org Date: Mon Jul 27 09:22:21 2015 +0200

Create debug mode

Wrap script in tmux, so that we can attach on failure. Disable status bar so that console output isn't full of escape codes.

Trap exits so that, if BENCH_DEBUG is set, we do not exit.

The two together let us log in, attach to tmux session and suspend. We can then debug in the environment where the error occurred.
