But forcing the existing JVM's to adhere to the current specification
requires the very implementation changes that I was referring to.
Given a choice between changing the implementation in a non-trivial
way, to "fix" something that is of little practical concern, versus
relaxing the spec, it's not hard to see what choice is likely to be

I'm not happy about this but I don't think we can avoid it.

I believe the VM must take responsibility for avoiding "lost
notifications", but that the relative order of interrupt vs. notify is
implementation dependent.
