Subject: [PATCH] Updated InternalRegistration Set method to update node if
 there is an existing node with the key instead of always inserting.  The
 always inserting functionality was causing a memory leak with the
 Unity.Interception because the PreBuildUp was always inserting a new node on
 every resolve.
