I'm not sure it's Safari per se. Safari is quite a "thin" layer around WebKit2. By "thin", I mean if you remove all the iCloud stuff, bookmarks, etc. Tab management intelligence is performed by WebKit2 backend process. So I think it's more of a testament to WebKit2 architecture. It's a real shame there is no good browser for Windows using WebKit2.
