Like externals it is not safe to expose blobs directly to JavaScript code.  You
have to wrap it as an internal field of a v8::Object.

+  Local<Value> reblob_obj = Script::Compile(v8_str("this.blob"))->Run();
+  v8::Handle<v8::Blob> reblob = v8::Handle<v8::Blob>::Cast(reblob_obj);
+  int count = reblob->ByteCount();
+  CHECK_EQ(3, count);
+
+  uint8_t b = reblob->GetByte(0);
+  CHECK_EQ(10, b);
+
+  b = reblob->GetByte(1);
+  CHECK_EQ(11, b);
+
+  b = reblob->GetByte(2);
+  CHECK_EQ(12, b);
+
+  uint8_t *p = reblob->GetAddress();
+  CHECK_EQ(10, p[0]);
+  CHECK_EQ(11, p[1]);
+  CHECK_EQ(12, p[2]);
+
+  p[2] = 52;
+  b = reblob->GetByte(2);
+  CHECK_EQ(52, b);
