When you write to /dev/null, the kernel always gives you back
the number of bytes you specified in the write as the return
value.  When you read from /dev/null, the kernel always gives
you back 0 as the return value.  On this Sun-3/160 running 3.2,
the kernel doesn't check if the second argument is a valid address
in the user's space.
