XNIO uses Selectors (usually PollSelectorImpls) which are cached per

starting many short-lived threads and doing blocking operations on

is basically "don't do that".
When you say "usually PollSelectorImpls" then it normally run with it
configured to use the poll based Selector?
BTW: Sean Coffey mailed me off-list so say that he tried the original
support/customer test case that lead to 7118373 and confirms that it
doesn't duplicate with 7u25.
Anyway, it would be good to hear more from Bernd to know if this
duplicates with 7u40 or 8. Also interesting to know if this is a case of
lots of short-lived threads doing timed reads on socket adapters (which
was the motive for replace this part of the implementation in 8).
