why CPU blocking must be taken as seriously as other kinds of blocking, consider password hashing functions like bcrypt, which by design use hundreds of milliseconds of CPU time, far more than a typical network background before triggering some future action in the application (as opposed to normal synchronous functions, which do every- thing they are going to do before returning). There are many styles of asynchronous Callback registry (e.g. POSIX signals) Regardless of which type of interface is used, asynchronous functions by definition interact differently with their callers; there is no free way to make a synchronous
