No, just assuming separate code and data segments.  Any executable code 
copies loaded from the same inode should be shared and paged in on 
demand (unless linux has learned nothing from decades-old unix).  If the 
copies were forked from a single instance instead of started 
individually they could also share data in copy-on-write pages until an 
instance changes a value.
