@instance methods inside custom views rmq_build causes memory leak

Finally started tracking down some of these things:

```
def rmq_build
@foo = rmq.append(UILabel, :tag)
end
```

will cause a leak where:

```
def rmq_build
@foo = rmq.append(UILabel, :tag).get
end
```

will not.

No file or test is named in the issue. Start by tracing custom-view rmq_build handling, then follow rmq.append and the .get path while reproducing both examples with UILabel; done means the instance assignment without .get no longer leaks.
