Your proposed solution is susceptible to the "lockstep starvation" problem. Lockstep starvation happens when two tasks try to get the lock at the same time and execute the same code in lock step, like so: task 1: lock |= 2; task 2: lock |= 4; task (...)

I have been working (when I should have been Working) on two things which may be of general interest. The first is a rotary electrical coupling, which allows you to pass 4 wires through a rotary joint. I built the prototype tonight, and I think it (...)
