Multithreading

The documentation makes multithreading look like a beautiful parade of orderly buses gliding smoothly down the street—so elegant, so synchronized, so *chef's kiss*. Then you actually implement it and suddenly you've got a catastrophic intersection pileup where nothing moves, everything's blocking everything else, and someone's honking their mutex in frustration. Race conditions? Deadlocks? A complete traffic jam of chaos? Welcome to the glamorous world of concurrent programming, where your threads are about as coordinated as buses trying to occupy the same physical space. Spoiler alert: physics doesn't allow that, and neither does your CPU.
