Ditto.

So, this is something I'm unclear on.  I know that static memory gets
auto-initialized to zero but what happens if you unload and reload a
module?  Is it re-initialized to zero?  If it is then we can drop
this.

Well it's not in memory after it is unloaded so clearly it has to get 
initialised by the module loader every time it loads it.
