weldon washburn commented on HARMONY-4908:
------------------------------------------

The (very rough) sync protocol kernel is contained in the three files StateTrans.java, synch_prototype.c and synch_prototype.diff.

StateTrans.java
This file contains a simple Java app that starts java threads which call Thread.sleep() with unique timeout values.  These unique values are intended to trigger specific behaviors inside sync_prototype.c.  The reason for spinning up Java threads from a Java app is so that the sync kernel can work with fully initialized java threads.

sync_prototype.c
This is a stand alone file that should be put in the working_vm/vm/thread/src directory.  The code in this file will be called by a special hack to thread_java_basic.cpp.

sync_prototype.diff
contains mods to a bunch of dlrvm files that allows the synch kernel contained in sync_prototype.c to be called.
