A big one is not using synchronization primitives when running multithreaded code.

Even with multiple cores, you can time your code such that if you're careful, since everything operates at fixed latencies you don't need to synchronize.

For example, if you're rending a frame on a separate thread than you're drawing it, you are a okay, as long as you're always rendering *ahead* of where you are drawing. The schedulers on these devices are very simple, so you can actually get something like interlocked execution even across cores. Interrupts interfere with this, but in some situations, you don't need to worry about that.

I'm in principle okay with this, because it saves CPU and thus power, but OMG is it nasty.

I just spent some time retooling someone else's code to be single threaded because I was getting heap corruption and they weren't using synchronization primitives. I thought that was why. Nope. Something else is going on. It's not crashing or leaking (as best as I can tell without a debugger) though. It's only even reporting because of some memory guards that wrap allocations. This is what made me think of this.

They are the ones we write code for, right?
