The old behavior of cp would try coping the device file to the new
location, which would obviously fail.

Interesting that cp can now be used to "cat" a device file.

-rwxr-xr-x 1 root root 31K Aug  5  2008 /bin/cat
-rwxr-xr-x 1 root root 76K Aug  5  2008 /bin/cp

Using cp instead of cat is going to cost you more then twice the memory.
And, again although negligible, it might cost a few extra CPU cycles
each time it loops.
