Libraries are EMBEDDED.  Yes I would expect the 213MB like you are seeing as well but it consistently boots up now with 310Mg + with NOTHING in the scene.  It's got a hold of something.  I just don't know what. I am pretty sure an uninstall / reinstall will correct it.  But, I wish I didn't have to do that.
