Re: JavaMemoryModel: Minor issue on hb edges and interrupts

Whether it employs hb or some other means, I think the spec should clarify
the following:

1. Do the interrupt and isInterrupted methods have to do anything? (or are
they similar to yield?)

2. Can these methods move into and/or out of synchronized blocks? Can they
move across volatile accesses?

Subject: JavaMemoryModel: Minor issue on hb edges and interrupts

There is a minor point that had been discussed before, but seems to have
gotten left out of the public review draft.

I am planning to add it back in:

  If thread T1 interrupts thread T2,
         there is a happens-before edge
         from the interrupted by T1
         to the point where any other thread (including T2)
          determines that T2 has been
         (by having an InterruptedException thrown
         or by invoking Thread.interruped or Thread.isInterrupted).
