You don't necessarily need to use max priority for sp.sched_priority.
There may be better ways of doing this, I guess... if anyone sees if
I'm missing something. Seems to work, but has the disadvantage of
having to run under "sudo" to gain the priority.
Depends on your system configuration. I don't have to call it as super user on
my system.
I'm not 100% sure if the mlockall call is
necessary.
mlockall avoids memory swapping, so as long as you haven't completely turned
off swapping in your system it's definitely a good idea to call mlockall in a
RT sensitive process.
If you're not a C++ hater, here's a general purpose "Thread" class which
can
be used for RT threads and low priority threads as well:

Just derive from that abstract "Thread" class and implement the virtual
method "int Main()" in your class.
