Is there a good reason why these applications should endure the present
heuristics of `pop-to-buffer' in the first place?  Shouldn't *Marked
Files* appear beneath the window where the marking took place?  That
latter window might not be the largest one and is almost certainly not
the LRU one, so the *Marked Files* window might not show up in a very
suitable place anyway.  I suppose the *Marked Files* window should be
obtained by first trying to deterministically split the window where the
marking took place and only when splitting fails have `pop-to-buffer'
find a suitable window.

So what I really need to know is how you (1) expect this to work
ideally, and (2) how to proceed when (1) fails.

As for the *Calendar* window I thought that Glenn wanted to do some
side-by-side splitting first because of the wasted space in a frame-wide
*Calendar* window.  So your proposal wouldn't help in this case.
