-// An interesting optimization for park() is to use a trylock()

-// in that case the park() code could simply set _count to 0

-// return immediately. That's harmless as the caller of park() is

+// In a sense, park()-unpark() just provides more polite spinning
+// and polling with the key difference over naive spinning being
+// that a parked thread needs to be explicitly unparked() in order
+// to wake up and to poll the underlying condition.

-// 3. In park() and unpark() add:
-// assert (Thread::current() == AssociatedWith).
-// 4. add spurious wakeup injection on a -XX:EarlyParkReturn=N switch.
