According to the README file of RTLinux driver mbuff (a shared memory
driver, part of RTLinux), the memory can't be swapped out.
I think RTLinux FiFos are also required to not be swapped to harddisk, but I
have no documentation at hand.
We use both methods, and haven't seen any problems there (but look out for
the acquired size of FiFo and shared memory).
