--- Comment #13 from Ben Nham <nham at apple.com> ---
This webpage is dying because the WebContent process it's running in hit a memory limit (X GB, varies by device). From looking at the logging emitted when the process hits the warning threshold limit, almost all of this memory is attributed to the JS heap:

```
WebKit memory usage statistics at time of warning memory pressure notification:
javascript_gc_heap_capacity_mb: 963
phys_footprint_mb: 1183
...
```

While it's possible that this is due to a WebKit bug, it's more likely to be a bug in the website itself. I'll try to use the Twitter web app to see if I see OOM crashes on it on my own device. But unless that uncovers an actual WebKit bug (e.g. use of some web feature that creates a document leak), this will have to be fixed by the website, not WebKit.
