Mahimahi shell dying.

When running bbr_experiment.py, sometime I see Mahimahi dying. Check if this error is important or it can be ignored.

Important. This shouldn't happen.

I will add a note that this was only happening when doing data collection for BBR.

I haven't seen this, and you haven't seen this again. I'm going to consider this resolved.
