Description Joseph Pecoraro 2017-06-20 17:16:20 PDT 
Summary:
Should be able to pause and debug an OutOfMemory Exception

Test:
<script>
s = "a"; while (1) s += s;
</script>

Steps to reproduce:
1. Inspect test page
2. Enable: Pause on All Exceptions
3. Reload the page
  => Should pause on Out of Memory Exception
  => Should be able to evaluate in console `s.length`

Note:
- Currently WebCore is spending time stringifying and sending scope / global variable `s` to the frontend. That should not be necessary.
Comment 1 Joseph Pecoraro 2017-06-20 17:26:22 PDT 
To address this we should be very careful about sending very large objects (like strings / arrays) to the frontend in one piece.
