------- Additional Comments from Dominic Cooney <dominicc at google.com>
Repro: Open LayoutTests/fast/workers/use-machine-stack.html.

Expected behavior: it prints PASS (RangeError: Maximum call stack size
exceeded.)

Actual behavior:
Safari 4.0.3 (6531.9): OK.
Google Chrome 4.0.212.1 (Official Build 26852) WebKit 532.1 V8 1.3.11.1: Worker
process crashes.

This is related to <http://crbug.com/21653>.

I've attached a patch. The patch depends on a proposed fix to V8 bug 442, see
<http://codereview.chromium.org/242014>.
