Paraphrasing the website: The ZThread package is an advanced object-oriented, cross-platform, C++ threading and synchronization library. It provides a high level abstraction of the native threading mechanisms to offer a great deal of flexibility and control. ZThread features interruptible Thread and Runnable objects for C++, control objects and implementations of concurrency design patterns. This includes semaphores, mutexes, condition variables as well as other more complex components. ZThread implementations are provided for POSIX and Win32 platforms.
