Yes, find all places where source->ref_count is incremented and check
for OBJ_ONEMAPPING as well as where OBJ_ONEMAPPING is set.
Then add some printfs to find the snippet that's incrementing it
to complain when the OBJ_ONEMAPPING bit is set, and complain if
setting OBJ_ONEMAPPING when the refcount is too high.
Blotting out a KASSERT isn't the right thing to do.
