Oh? ok. In the script you sent, it is not active (verletDist is negative
by default). By making it 0.3 radius, I can get down to 1 each 10
iterations.

Valgrind always give interesting things, attached is some output for
InsertionCollider (with your script): 40% of collider time is spent in
the "find(id1,id2)" function, mostly because of shared_ptr manipulation.
A bit surprising...
