What's this all about?

BTW, tabs are a bad idea in source files.

You need to return an array-like object in *vp here.  That object's 
getter, or a predefined element at the index given by JSVAL_TO_INT(id), 
is what would contain the child object.

You're missing a level of object indirection, in other words.  The id 
here is 'child', for an expression like 'p.child'.  The expression 
'p.child[40000]' involves another getProperty after the one you've 
implemented here, which runs with obj bound to the object denoted by 
'p', and id to 'child'.  So you need an array, or an object that acts 
like an array.
