Description
GC cannot garbage collect objects in a for yield, as long as they are in scope
We need to help it by putting them out of scope, or not referencing them anymore, or by returning smaller objects
see https://github.com/Normation/rudder/pull/2648/commits/e916e3ebe2c5d5b8299f2b0953b9739ebbe08f42 - it saves a full GB of memory during policy generation
