Again, there is choice.
You have it your way, I'll have it mine.
As far as I can tell ...
(SeaMonkey) loads the first window, then loads all the other windows, then (in my case I have it set to load 0 tabs upon Session Restore) it moves sequentially through each window, loading the current tab in each, & dumping back where you last were before quitting. (In what sequence it does if you load all tabs automatically, I'm not sure?)

you can't tell when all are loaded except by mousing over each tab or watching Task Manager for CPU usage
What are you trying to say? That MS neglected to put a network indicator icon in Vista & Win7 so that you can quickly & easily monitor such things? (I suppose there is always hope for Win8, NOT!)
