Small threading library to demonstrate how one might implement threads on an x86 CPU. Not meant to be used for any heavy-duty lifting, and is meant for learning.

Run make to get a binary called echo_server in the example directory, which shows how you can use fthreads to write a simple, multithreaded network server without having to change much from a pthreads implementation.

Wanna take it for a spin? Just #include <fthread.h> in your project, and compile with -lfthread.

In addition to userland context switching, fthreads provides a more elegant solution to IO multiplexing than standard calls to poll or select because you can still write code in a style that looks like threads. The scheduler is doing the multiplexing for you behind the scenes.
