hi bengt,

my code was just making a statement and is indeed incorrect.

i do have quite some code which relies on {packet, http} and passive
mode, so i believe i might be confronted with adding code which
handles running on different versions of the erlang VM. *if* i'm
not misunderstanding, this does break backwards compatibility and i'm
quite surprised, to the point i'm asking this list for confirmation.
