Problems with IPC

I have found there is a possibility to speed up the microwindows system. 
Up to now, all data is passed through a socket interface. Microwindows 
has the option to use shared memory for this.

Shared memory is not activated in the kernel. In the net, I have found:

Can someone try to enable shared memory support for DSLINUX?

We're back to the times when men were men 
and wrote their own device drivers.
