<pre>There should be 2 separate reserved zone sizes for JS and host code (we currently only have one reserved zone size for both), and the JS code reserved zone size needs to be larger than the host code reserved zone size. For example, the JS reserved zone size needs to be large enough to provide sufficient CPU stack capacity for the max recursion taken by the parser to recurse when parsing any builtin. In contrast, the host code reserved zone size only needs to be large enough for one recursion entry into the parser.</pre>
