Summary: /dev/full

I suppose this is already in Version N. . .but what I have a use for every
month or so is "/dev/full"--so that I can do a dumb timing test this way:

	dd if=/dev/full of=/dev/rmt8 bs=20b

While /dev/null always says "I successfully wrote as many bytes as you asked
me to", /dev/full would always say "I successfully read as many bytes as you
asked me to."
