investigate the trick with enter local scope and not to copy strings

[peter-leonov]

If it is possible to protect every string is used in the request from garbage collecting till the request is gone, we can forget about copying all the strings bytes, just use the JS_Malloc'ed memory.

Also the data exchange between the JS engine and the engine X will be greatly simplified.

Check this.

Oh, and the GC-rooting of the request wrapper becomes unnecessary! :)

[peter-leonov]

JS_EnterLocalRootScope() and JS_LeaveLocalRootScope() work with a stack. So an overlap may occur leading to an alive objects collecting.

Also, ATM, we can't get a local root token to emulate a named root scope and enter/leave it many times, then collect. Will try to emulate this manually with arrays or something kinda like.
