Portable Multithreading-The Signal Stack Trick for User-Space Thread Creation

This paper describes a pragmatic but portable fallback approach for creating and dispatching between the machine contexts of multiple threads of execution on Unix systems that lack a dedicated user-space context switching facility. Such a fallback approach for implementing machine contexts is a vital part of a user-space multithreading environment, if it has to achieve maximum portability acros...
