commit 538f51e50da7207a921694ac641302a2ce2c85cc 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.
