Description
A comment from the JDK-8153224 review thread:
> Most of the comments in the CR8/v2.08/11-for-jdk14 code review cycle were
> on the monitor list changes so I'm going to take a look at extracting those
> changes into a standalone patch. Switching from Thread::muxAcquire(&gListLock)
> and Thread::muxRelease(&gListLock) to finer grained internal spin locks needs
> to be thoroughly reviewed and the best way to do that is separately from the
> Async Monitor Deflation changes. Thanks to Coleen for suggesting doing this
> extraction earlier.
