It also prevents drives from unmounting when logging out.

I've been running OS X since the Public Beta (OS X Server 1.2  
actually, but that was really a totally different beastie). I  
distinctly remember this behavior change with Jaguar (might have been  
Panther, but I'm pretty sure it was Jaguar) and being rather  
irritated by it. The above defaults command became necessary to  
prevent the firewire disk that I back up my home server onto from  
unmounting at logout. Google should still be able to find discussions  
of the topic for you.
