I wonder if it's not better to use unsafe.tryMonitorEnter()
instead of a lock bit.
I need a lock with a form of tryLock, so while I do use built-in
monitors and/or AQS for actual locking, I need to preface use with
lock bit
in regular non-tree-bins.
tryMonitorEnter is the equivalent of tryLock for synchronized block
(monitorEnter/monitorExit).
Also the class depends on LongAdder, is it a requirement or an
AtomicLongUpdater
can be used ?
If this ever makes it as far as contemplating JDK7 ports, a minimal
form of LongAdder could be pulled in as a static inner class.
