Ok -- then read, from powerd src...

# "config_MESH_DURING_SUSPEND" (boolean) controls whether the
# wireless remains powered while the laptop is fully suspended
# (i.e., sleeping with a dark screen).  The only reason to set
# this to "yes" is if you want the laptop to forward packets for

It does so by accident, and with a heavy power use cost (for you).

To be clear, I think this is missing functionality in powerd.

Anyone wanting to run 10.1.3 builds on XO-1 with the new ad-hoc
networking model, and without mesh will hit this same problem.
