Handles of this type are automatically reset by the garbage collector when their objects are not longer reachable. The motivation is to reduce pause time of external.weak_global_handles phase of the garbage collector by not maintaing the list of pending callbacks and not calling the callbacks. Local testing on discourse page of the v8.inifinite_scroll benchmark shows 7x improvement for this GC phase. Before: external.weak_global_handles len: 21 min: 0.0 max: 4.5 avg: 0.757142857143 After: external.weak_global_handles len: 21 min: 0.0 max: 0.5 avg: 0.109523809524 A follow-up patch will enable the new phantom handles in Chromium.
