an obvious consequence of the change is that pagedaemon picks up
->K loaned pages.  we have choices how to deal with these pages.

	1. "pageout" the loaner side of the page by breaking the loan.
	   (the page will be freed when it's unloaned.)

	2. skip the page, maybe by activating it.

my patch does #1.

it shouldn't matter as far as durations of loaning are short.
it could make differences for eg. a pipe which is rarely read.
