ostest RR scheduler testing

[TaiJuWu]

I have a question about RR scheduler

nuttx-apps/testing/ostest/roundrobin.c

Line 227 in d73e641

"If RR scheduling is working, they should start and complete at\n");

The comment shows thread_1 and thread_2 should start and complete at about the same time.
But I did not see any assert condition about it.

Is it needed to modify or it is correct?
I try to add some assert to this problem at
https://github.com/TaiJuWu/nuttx-apps/blob/30038063e2b9958202118d4b4c3724eec7069622/testing/ostest/roundrobin.c#L254
Im not sure it's useful and is this method great?
If anyone can give me some suggestion, I will be very grateful.

@TaiJuWu I think this could be a good idea! We need more people testing RR SCHED. Did you have chance to test RR with Tickeless mode?

[TaiJuWu]

No. I just used nsh:smp as my default setting. I will try using tickless mode this weekend.

It also can work on qemu-armv8a:nsh_smp_tickless but why we need to use tickless mode?
Actually, I can't image what condition will make this test fail....
