Like a Google Instant search of your browser history.
Eg. If I hit Cmd-L, then type "omni tab" this page pops up.
Unfortunately, that doesn't resolve the issue if you were closing a bunch of things and accidentally closed one-too-many and you don't know what the title of that window/tab or its contents at all. When dealing with 200+ open windows and tabs that get replaced with another 200+ on an hourly basis, combined with not knowing the name of the page, looking through the history or using the location bar to try to figure out what it was can be an annoyance. Safari and Chrome both have the "Reopen Last Closed Window/Tab" feature... although, Chrome's implementation is more unified for both tabs and windows. (Safari relegates tabs to "Edit > Undo" and windows to "History > Reopen Last Closed Window" for the Window. (In Chrome, it can be a single tab, a single window, or a window of multiple tabs... really it's about undoing the last close operation, for whatever that close operation affected....)
To be honest, we could probably just do away with the menu clutter of having a dedicated menu item for "Reopen..." and just have it all as Undo actions.
