mgorny added a comment.

I don't think we can reliably check whether additional threads aren't run then.

I have another idea that could work better if we could assume that the 
scheduler runs threads of the same process somehow evenly — or well, I suppose 
it'd be better in any case. Rather than stopping the process from LLDB, I could 
add a counter that issues SIGSTOP from inside the process after doing N (say, 
5) prints. I suppose that should give it enough time for all threads to output 
something.

Just need to figure out a simple synchronization method to ensure that SIGSTOP 
is emitted only once.
