This is a fork of https://github.com/tibogens/OpenThreads/commits/master to provide a simple way for building only the OpenThreads library.
It is randomly aligned to upstream: https://github.com/openscenegraph/OpenSceneGraph.

This library is intended to provide a minimal & complete Object-Oriented (OO) thread interface for C++ programmers. It is loosely modeled on the Java thread API, and the POSIX Threads standards. The architecture of the library is designed around "swappable" thread models which are defined at compile-time in a shared object library.
It is of importance to note that while a factory pattern design could have been used to achieve the goal of genaric interface, it would have required the programmer to allocate each of the 4 fundemental types (Thread, Mutex, Barrier, & Condition ) on the heap. Due to the cost associated with heap allocation for some of these constructs, such allocation was deemed unacceptable, and thus the factory pattern was not used.
Instead, a somewhat obtuse - but effective - technique was chosen to provide the necessary data/implementation hiding. This technique uses private void pointers to encapsulate object private data. The void pointers actually point at concrete data structures, but give a uniform interface to the dso.
