 We'll be coming back to cancellation and cancellation safety a few times in this guide, and there is a whole [chapter]() on the topic in the reference section.
 
-[^cfThreads]: It is interesting to compare cancellation in async programming with canceling threads. Canceling a thread is possible (e.g., using `pthread_cancel` in C, there is no direct way to do this in Rust), but it is almost always a very, very bad idea since the thread being canceled can terminate anywhere. in contrast, canceling an async task can only happen at an await point. As a consequence, it is very rare to cancel an OS thread without terminating the whole porcess and so as a programmer, you generally don't worry about this happening. In async Rust however, cancellation is definitely something which *can* happen. We'll be discussing how to deal with that as we go along.
