It is a stalemate and the ref should not allow the wrestler on top to just "soften up" the bottom guy with elbows - wrestling is not the UFC or MMA. You can use pressure to work for a fall but not drop elbow bombs. Driving on the wrists to get a power half would be working for the fall.

When wrestlers are in a specific position where it is unlikely that either of them will be able to score, the referee will call a stalemate and the wrestlers will be reset in the appropriate starting positions. To signal a stalemate, the referee will curl the fingers of both hands and touch his knuckles together in front of his body.
Illegal Hold & Unnecessary Roughness
If a wrestler uses a technique that is deemed illegal, or is unnecessarily forceful when performing a specific move, the referee will blow his whistle to stop the match. He will then raise his arms and touch both of his palms to the back of his head. He will then award points to the appropriate wrestler.
