A quick explanation in case anyone else wants to know why this works:
this part "3>&1 1>&2 2>&3" swaps stderr and stdout (so errors show up on stdout
and non-errors show up on stderr)
then tee copies the *swapped* stdout to the file /tmp/junk.err, so error
messages end up there
both stdout and stderr are then copied to junk.log ({>&} copies both outputs to
one file), it doesn't care that they're
swapped around.
