The inter-process communication used is a combination of semaphores
and shared memory.
The engine sends a start signal to the bot, then waits on the return
semaphore with a certain timeout.
If all bots set their orders and return in only 0.1 seconds, that's
fine! The engine will start the next turn much quicker, because it
didn't have to keep waiting.
If it times out, then it'll only process the orders of those who returned.
