If ZTS is disabled , the v8js_globals instance is declared right
in the BSS and hence automatically initialized by C + + compiler .
Most of the variables are just zeroed .
If ZTS is enabled however , v8js_globals just points to a freshly
allocated , uninitialized piece of memory , hence we need to
initialize all fields on our own . Likewise on shutdown we have to
run the destructors manually .
