To see how this is being handled in Xen currently, I suggest you to
grep for:
ple_gap
ple_window
SECONDARY_EXEC_PAUSE_LOOP_EXITING
EXIT_REASON_PAUSE_INSTRUCTION
pauseloop_exits

I am aware of your paper, but I haven't got to being able to read it
carefully yet. I'll do that (but can't promise when).
