[d]ets:lookup misbehaves when called during init:start?

[Chris Pressey]

I have discovered one workaround for this, although it comes at a grave
cost (namely, the use of the shell)

Instead of

  erl -run module function

use

  echo 'module:function().' | erl

Should have been obvious I suppose :)
