Feature #7923: Queue#push and Queue#pop makes trap safe

Currently, following program don't work because q.push raises an exception.
However, it would be nice if queue is trap safe and Queue#push and Queue#pop can be called from trap handler.

------------------------------------------
require "thread"

q = Queue.new

trap("USR1") {
  q.push(nil)
}

Process.kill :USR1, $$
sleep
