Description Mark Lam 2014-01-09 13:21:49 PST
The "zone" is used as a reserve of stack memory for:
1. nominal host code stack usage.
2. stack space for error handling.
3. initial stack space for pushing VMEntrySentinel frames.

The "zone" may reside on the C stack and on the C loop JSStack depending on context.  Hence, the name "host zone" is not quite accurate, and we'll rename it to "reserve zone".

Patch coming.
