 * DESCRIPTION
 *    The test creates a mutable call site and relinks it from one thread while calling target from
 *    the other one.
 *    The test verifies that target changes in the call site are eventually seen by target calling
 *    thread by comparing the number of just called target with "golden" one, supplied by target
 *    relinking thread.
 *    For internal synchronization between the threads the test uses a non-volatile variable
 *    without any synchronized() statements or java.util.concurrent classes.
 *    The test artificially loses synchronization sometimes to verify that test logic is correct.
