| When running several SMP applications in parallel instances of Qemu, |
| e.g. via twister, explicit serialization may be required between |
| pthread_create() and zephyr_thread_wrapper() when spawning and joining |
| many pthreads concurrently. |
| |
| On such systems, say Y here to introduce explicit serialization |
| via pthread_barrier_wait(). |
