Environment

Windows 10, Version 1803 (OS Build 17134.48)
Chrome Version 66.0.3359.139 (Official Build) (64-bit)
Firefox 52.7.3 (64-bit) -- I couldn't find a Chrome-equivalent Task Manager, but using Windows's Task Manager I could see that Firefox's memory usage steadily increased, and the README was the only tab open.

Steps to Reproduce

1. In Chrome, open up https://github.com/facebook/create-react-app
2. Press ctrl + esc to open up Chrome's Task Manager.
3. Watch as the tab gradually takes up more and more memory.

Note: When I ran Chrome's memory profiler, I could not find where the increased memory usage was coming from. The heap remained at a constant 6.3MB, and no new allocations were detected over a span of about 20 seconds despite memory usage steadily increasing.

Expected Behavior

Memory should remain constant as it does with other github READMEs.

Actual Behavior

Memory did not remain constant; it gradually increased. Over the span of about 15 minutes, it increased to over 1 GB.

These screenshots take place over the span of roughly 2 minutes.

I suspect this is a bug with webpack-dev-server; can you please file it with them? I'm going to close this issue because we're switching away from webpack-dev-server soon and I'm not sure if webpack will commit resources to this on an old repo.

Thanks for the report, this gives us more reasons to switch libraries!
