I agree and I assume you will replace it with an embedded Map. I suspect 
it will be hard to see a difference (with the server VM anyway).

The typical NIO server tends to handle lots of concurrent connections so 
with a relatively small number of threads (one per core for example) and 
a small number of Selectors. It sounds like your server might be 
different. Selector creation is relatively expensive so you might run 
into issues there.

The idle set is almost always empty and an aside from one case, there 
shouldn't be any boxing when the set is empty.

Mark and others are working hard to make this happen very soon. As I 
understand it they have some infrastructure work to complete before they 
can allow changesets to be pushed.

I look forward to it.
