RTAI native skin RT pipes :

(the doxygen documentation is also part of the fusion tarball).

mmap should work for user-space threads. I am not sure that the mlockall
call in Fusion library is enough to avoid page faults though... So,
right now, just after calling mmap, you should cause a fault for every
page in the mmaped zone (using memset, for example).
