I was wondering if we wanted to introduce something like this on the front end
(a wrapper around SharedBuffer + Vector<BlobInfo>).

Hmm...could be.  Not sure if it'll be worth it yet, but we can always do it
later.

+  IndexedDBValue() {
+  }
+  IndexedDBValue(const std::string& input_bits,
+      const std::vector<IndexedDBBlobInfo>& input_blob_info)
+    : bits(input_bits),
+      blob_info(input_blob_info) {

DCHECK that empty bits -> empty blob_info ?

[ericu, 2013/11/20 23:05:39]

Done.

+  }
+
+  void swap(IndexedDBValue& value) {
+    bits.swap(value.bits);
+    blob_info.swap(value.blob_info);
+  }
+
+  bool empty() const { return bits.empty(); }
+  void clear() {
+    bits.clear();
+    blob_info.clear();
+  }
+
+  std::string bits;
+  std::vector<IndexedDBBlobInfo> blob_info;
+};
