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).

Regards,
Dario
