A simple co-routine implementation in modern C++

A very simple implementation of an M:N threading model similar to the one used by Go's Goroutines and many other user-space threading libraries that implement co-routines (for example, C++20 and Kotlin).

We use round-robin scheduling using a queue of waiting user-space threads to schedule them onto a fixed number of kernel threads (specified using the system_init function).

Build Instructions

Use the provided makefile to compile the built-in driver program to demonstrate that our implementation progress without deadlocks.

make all # generates test binary

./uthreaddriver

make clean # cleans up build artifacts
