No, that's Linux with prelink installed.

Perhaps this might be a hard concept to wrap one's brain around, but there's  
a quite a bit of difference between "this is an exceptional event, and  
that's what happens when i does", versus "this is now a normal occurence  
that, with prelink installed, and can happen to any random executable, at  
any time."

Across the pond, I believe that there's a word to describe this: "rubbish".  
How presumptious of an executable binary, that's not world-writable, to  
expect that nobody's going to come around, suddenly, and delete it! What  
would those kids think of next…

Sure. And since gruesome car wrecks are a normal, everyday occurence,  
there's no reason to do anything to davoid them. That's how they always  
work, and anyone will just have to deal with the aftermath, without  
bothering to take any steps to avoid the situation in the first place, right?
