   @reinhapa 
   I have several experiences with the influence of GC load to the locking and reorderinng due to delay caused by the GC, especially on MacOS. I think this is similar issue with JVm on Windows because `-verbose:class` prints many logs and overloads the process much more than `-verbose:gc`. I guess the Win impl of JVM has some weaknesses in this case. Maybe a nice solution would be to implement `CompletionHandler` and use `CountDownLatch`. Maybe it would be better than having some sleeps and loops, etc. We are aming for getting faster and faster JVM startup and teardown since we made a big investment to speed up the JVM in M5.
