What I did instead was exit the cold cloud, boosted away in a random direction about 20 klicks or so and tucked myself into a collection of 'roids and made like a rock, shutting down all nonessential systems to keep the signature low.
Could easily have run out of fuel, but 20km is not far and I would not be surprised if an NPC wandered over saw you had cargo, and blew your CMDR's ship away when it didn't promptly drop cargo.
And never ever ever (!) afk.
I go afk all the time, I just make sure my CMDR's ship is not stationary unless it's docked. Speed is life.
