Hi:
OOh, the original author here! Thanks a lot.
Let's assume Mn is the total number of non-resident pages in follow words.
Nod, 'M=Mh+Mc' and 'Mc+Mn' < 2M are always true.
Have this implied that Mn is alway less than M? I think so.
but if "Once the number exceeds M the memory size in number of pages, we terminted the test period of the cold page pointed to by HAND-test."
If Mn is alway less than M, when we move to HAND-test?
Or, my view have error.
I doublt on this, in fact.
Good luck.
Liyu
