* VM Testbase comments: 8079664
* VM Testbase readme:
* DESCRIPTION
* The test creates a volatile 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.
