This configuration has basic support for SMP testing. The simulation supports
the emulation of multiple CPUs by creating multiple pthreads, each run a
copy of the simulation in the same process address space.

In this case there is, of course, no multi-CPU processing, but this does
verify the correctness of some the basic SMP logic.
The NSH configuration can also be forced to run SMP, but suffers from
the same quirky behavior. I can be made reliable if you modify
the same quirky behavior. It can be made reliable if you modify
arch/sim/src/up_idle.c so that the IDLE loop only runs for CPU0.
Otherwise, often simuart_post() will be called from CPU1 and it will
try to restart NSH on CPU0 and, again, the same quirkiness occurs.
