Coroutines are safer for two reasons. The first is that synchronization is
in the programmer's head, while with threads and processes synchronization
is done by the operating system. With coroutines you have no deadlocks or
race conditions to worry about because you get to explicitly choose your
synchronization points.
But the main point is that coroutines are written for a single processor
world. They emulate parallelism inside a single process. That's what really
make them safer. But this is not helpful in a world of multiple cores. One
still have to choose between threads and processes for large scale
multiprocessing.

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
