I also observe from the source code that v8 engine provides a public
API
v8::V8::Dispose() function to tear down the v8 engine permanently. I
think
this function is suitable to me for shutdown the v8 engine in
anplication when
the wrapping javascript service no longer needed. However, I have
tested this
function but some of static global variable which allocated in setup
still does not
free. Is it sometime that i have done wrongly??
