A module is part of the same process and therefor subject to the GPL
(it is linked). The GIMP uses another approach where every extension
is an own process and communicate with the main program by shared
memory. So it is possible to write a GPLed module which forks and
execs the non-GPLed module .... (but see my sig)

Sure. But at some point we have to stop adding features until a real
