Re: RFR(s) #2: 6344935: (spec) clarify specifications for Object.wait overloads

[Martin Buchholz]

Here's a plan: Stuart commits his improvements, we then improve the code
snippet in TimeUnit.timedWait, then change wait(long, int) api note to
point at that.  We can also add a "time-less" wait loop code snippet to the
spec for nullary wait().
