While working on the fix for the following bug:

    4510838 4/2 self-suspend race with GetCallTrace

I dug up some tests that I wrote for 4413752. One of these tests
hangs using Merlin-B80 on Solaris SPARC:

java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b80)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b80, mixed mode)

Setting diwait4413752_EventHook as event hook.
######## JVMDI_EVENT_VM_INIT ########
About to execute 6000 loops
Exception in thread "main" java.lang.InternalError: resumer thread is stuck

        at diwait4413752.main(diwait4413752.java:72)

The failure indicates that waiter thread was granted ownership of an
ObjectMonitor during a wait() call even though the thread was suspended.
