Better vertical spacing in 2.11 adversely affects lyric spacing

[Monk Panteleimon]

It appears that 2.11 is trying to keep single staves from occupying their
own (last) page. That's a good idea too but, at least in my case, it seems
to be doing so at the expense of good lyric spacing in a ChoirStaff.
Lyrics should be equidistant from higher and lower staves, right? Instead
they are winding up close to the top staff and far from the bottom.

In this file:

you can see that if you compile it with 2.11, the page breaks before the
last system, but the lyrics get stuck to the top staff. With 2.10, the
lyrics are centered between the two, even if you put a \pageBreak before the
penultimate staff.

I do hope that this will be fixed by the next stable release so that I can use 
nifty top-level \pageBreak that is the boast of lilypond 2.ll.
