You do not want synchronized and "visibility semantics pretty close to
the JMM" as your primary concurrency mechanism visible at the
high-level language level, or where anyone short of a Damian-level
hacker can easily get at it.

Sure, that may well be what your virtual machine (or equivalent
hardware abstraction layer) wants, but don't, for the love of Mike,
expose it in the HLL. That's pretty much the biggest lesson learned in
the last 15 years of implementation decisions in the JVM.
