filling /dev/null

[Frank Perdicaro]

While testing a few things on a 4D35, I decided to see how the added memory
bandwith would effect kernel data movement activities.  Just for a lark, 
I tried
   dd if=/dev/zero of=/dev/null bs=256k count=256k
All went well for a while.  Then, I got a EFBIG exception from dd.  
Somehow this is both not surprising, and not appropriate.  Considering
the special way /dev/null is handled by the kernel, should it not
be exempt from this type of accounting?  Anybody care to comment?

It really seems odd that one can 'fill' /dev/null!
