Is 3.12 intentional?

[hans, 2010/12/09 17:42:30]

Yes, but there's no deep rationale for it. Just figured we shouldn't always set
the bound to the exact value.

   var result = objectStore.openCursor({range: keyRange});
   result.onsuccess = cursorSuccess;
   result.onerror = unexpectedErrorCallback;
