I do have it, but but the problem is that I don't need one, but unknown 
number of pipes. If I go through loopback interface with AF_INET I must 
include some counting to avoid two threads listening on the same port 

I have checked out how socketpairt is done on linux, and they make a 
socket and asign two filedes to it, but in rtems code there is call to 
rtems_panic if there are two threads waitng for the same socket :(
