Again, if I am not mistaken, the while loop is needed if there is more
than 1 reference to the pbuf in question. Perhaps, in this particular
program this will never happen. Maybe the author of the code put the
while loop there just to be on the safe side?
As for pbuf_dechain(), I'm not sure it's the right function to use.
You still have to free the pbuf, and pbuf_dechain() doesn't seem to do
that.
