I am working on an app that is about 700K in size, and so I decided to
look at this great new 2.0 feature to reduce the initial download. The
app is pretty moduralized, so it seemed like a good candidate for code
splitting -- each module should download its code only once it's
accessed for the first time. After playing around with the split
points, I've, for the most part, achieved the desired behavior, but I
am running into a problem with the "left over code" chunk.

Different modules within the app reuse the same components (usually UI
widgets, but sometimes business components as well). Since these
reused components are not specific to any one module's split point,
they all go into this general "left over code" bucket, which is fine.
The problem is that since there is only one leftover bucket,
*everything* ends up in it, including even very small UI pieces that
may be required by the initial download, but are shared with other
modules eslewhere in the app.

The end result is that I've cut down the initial download to 120K, but
what I'm observing is that right after the initial download, the app
is downloading the leftover chunk, which is quite large in size since
it contains all of the common components of the app. This seems a bit
counter-productive.

So my questions are as follows:

- Is there some nice way to split up the leftover chunk? Ideally what
I'd like is to have a chunk which contains just the common components
required by the initial download, and then another chunk which has the
modules' common components, which is to be downloaded only once one of
the modules is accessed.

- If not, is there some other pattern that can be recommended to
prevent this almost-initial download of the leftover code chunk?

Thanks!
