Well, as I presume that only one instance is ever created, that check is 
almost free and would catch the rather fatal bug if it was created twice. 
Likewise with the destructor: While unlikely, the check is nearly free (could 
be an assert, even) and is a nice sanity check. I admit I might be too 
paranoid there. Blame my IT career ;)

Ah. Well, that's not much of a concern, then.

ok, so maybe I was too paranoid. All my alarm bells just went of when I saw 
the code. No offense meant! (I would still add the constructor check, at 
least as an assert) :p )
