If you know exactly where you want the page turn to happen, you can
leave the Page_turn_engraver out and specify the turn with
\allowPageTurn. In general, if you prefer page turns only after longer
rests, you can set the context property minimumPageTurnLength to
something larger than the default.

The page turn algorithm isn't very flexible in this regard: it only does
page turns after odd-numbered pages. If you don't want a page turn after
the first page, you need to set first-page-number to 2.
