Is it possible to do communicate a thread posix real time and a thread posix
non real time?
Can we create a thread posix non real time with some options?

No, the native skin has such a feature (message pipes), but this feature
has no incarnation in the posix skin.

The way to do this with the posix skin is to create a thread with
SCHED_OTHER policy and priority set to 0, and to have this thread
communicate with real real-time threads with a posix message queue and
do non real-time duties.

To create a non real-time thread, use __real_pthread_create instead of
pthread_create.
