This is an essential truth of async in its purest form: There is no thread.

The objectors to this truth are legion. “No,” they cry, “if I am awaiting an operation, there must be a thread that is doing the wait! It’s probably a thread pool thread. Or an OS thread! Or something with a device driver…”

There is no thread waiting for the operation to complete is their point.
