Inspired by the Ivanchuck waiting move 9. ..Re8! in the Accelerated Classical, how about 9. ..Re8, so after e5, e4 is immediately under threat, but Black isn't committed to e5 just yet.
It does look like a constructive move with some points behind it. To avoid going into something like the following related series of moves (not liked by Marin, see "Grandmaster Repertoire - The Pirc Defence", p.62)
(1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Nf3 Bg7 5.Be2 0-0 6.0-0 c6 7.a4 Qc7 8.Be3 e5 9.h3 Re8 10.dxe5 dxe5 11.a5)
A practical point, whenever you've played e5 as black, would probably be to try Nxe5. For example:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Nf3 Bg7 5.Be2 0-0 6.0-0 c6 7.a4 Qc7 8.Be3Granted not really the move order discussed earlier. Moving on though...
8...Nbd7 9.h3 Re8 10.a5 e5 11.dxe5 Nxe5and we've avoided something similar to the above line.
Or you can try postponing e7-e5 for a while longer. In fact...
Using your 9...Re8 it seems like Ulf Andersson managed to achieve a result that was satisfactory (for both parties

).
Have a nice day.
