Subject: [PATCH] Clear TT before running 'bench'
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Now that we can call bench multiple times
from command prompt we need to ensure searched
nodes remain constant across different runs.

Spotted by Bálint Pfliegel.

No functional change.
