Review Comment:
The conversation/review here discusses this yesterday between Kevin and I.
I'd like to propose that we have a separate dedicated work item that has the
goal of *nobody* calling the integer single-arg constructor to HashMap or
HashSet, as it's a trap/gotcha (with probably minor down-side, granted). We
can add a utility method for creating pre-sized maps or sets.
