Here we go:
[fen]8/8/3k4/8/8/8/PPPPPPPP/KQ6 w - - 0 1[/fen]
SwissGambit's example sent me in the wrong direction (as it was probably intended to!).

41. b7 Ra7 {Now White breaks the pin.} 42. Re1+ Kd8 {Keeping the b-pawn pinned.} 43. Re7 {And wins.} [/pgn]
I think you meant 'Faff around for 20 moves bemoaning the fact that you never bothered to learn QvR endgame, then offer draw'.

In the study/problem world any book win/draw is taken as such.
but Rank Outside is correct. A lot of these KQ v KR endings are drawn.
I have 393 such endings on RHP - 101 were drawn. (approx 25% )
This pattern crops up quite a few times as a drawing method.
ydnas -HFRAtomHeartDude RHP 2011Game 8410760
White played 87.Rf3+ and 88. KxR is Stalemate.
Sometimes all you need to defend is your opponents bad play.
Slappy Stan - RedHotHermione RHP 2011 Game 8260921
Black played 68...Kh1. 67.QxR Stalemate (67. KxR wins)
You can simply just give up.
Erebos - snjortp RHP 2011 Game 8362178
White had faffed about for a few moves -
decided he was getting nowhere and played 67. QxR+ ½-½
And then of course you can faff about for your full allocated 50 moves.
Game 7594926 Quirine - caissad4 RHP 2012
RHP informs us: '50 moves without a capture or pawn move Game drawn.'
This idea appeared a few times in that game and was missed.
