In the above position, my search tree explodes because of extensions. It takes >
3 minutes and 42 million nodes to finish an 8 ply search. How does your program
do?

Any good ideas on how to limit extensions in such a position.

P.S. Solving the position is no problem. It is a simple mate in 5 plies, and is
found very early on at depth 1 or 2 or so. Still, there must be something
unsound about my extensions, or at least room for improvement, when this
position makes the tree explode.
