Investigate why tomo_step_scan caused an outer loop to fail #20
Description
During 2018-03-10 beamtime, I set up a simple script that continually exectued tomo_step_scan and energy_scan. It only executes tomo_step_scan on odd numbered loops (1, 3, 5, etc). After the first tomo_step_scan (iteration 1) the script just ended. Log shows no exceptions were thrown. Since iteration 0 completed successfully, it's actually looping and it's not a question of using if instead of while or something like that.
