- Synchronization:
- All of the objects that pthreads creates have built in synchronization in the ( familiar to java programmers ) form of ::wait and ::notify. 
- Calling ::wait on an object will cause the context to wait for another context to call ::notify on the same object. 
- This allows for powerful synchronization between Threaded Objects in PHP.
