When configuring your kernel, configure the posix skin as a module. A
module xeno_posix.ko will then be compiled that you may load with
modprobe and unload with modprobe -r.

Shared memory are also accessible to non-rt tasks. Since user-space
realtime and non-realtime threads from the same process reside in the
same address space, the simplest way to share information from rt to
non-rt tasks is to create them as threads of the same process.
