[COFF] Shell script advice: using 'dd' to write multiple media

[Steffen Nurpmeso]

And i'd wish the shell had "set -o pipefail" much much earlier.
So you (sometimes) do things like

  #(set -o pipefail) >/dev/null 2>&1 && set -o pipefail
  es=$(exec 3>&1 1>&2; { the_worker "$cmd"; echo $? >&3; } | mytee | mymail)

that are super neat (ie that this is possible syntax-wise!), but
terrible and cryptical and surely error-prone to do.
