But I think we _should_ decide which kind of initialization we use. In sockets.c, the sockets array is not initialized (trusting the linker/startup code will do so) while in udp.c and other files, double initialization is done.

I think a good solution would be to require the target can do static initialization and put some kind of an ifdef around initialization to zero, so that it can be configured in which section such variables are put (initialized by including in the binary or initialized by the startup code).
