win: os_proc_tree_kill()

XXX: comment at https://stackoverflow.com/q/1173342 :
> Windows recycles PIDs quite fast, you have to be extra careful not
> to kill unrelated processes. These APIs will report PPIDs for long
> dead processes whose PIDs may have been recycled. Check the parent
> start date to make sure it is related to the processes you spawned.
