• Saw Timeout on reading from ophyd_async if not read from ophyd first dodal#791 again
• Having the two use_cpu_and_gpu_zocalo and use_gpu is confusing and enable_dev_shm was only being set on use_gpu. Fixed by setting on the or of them both
• Issue where if the there was no diffraction and no results from zocalo the comparison of the results would fail
