I'm not convinced that an application that creates 400 threads and
exits in 10 seconds is particular representative of a high-performance
application.

But I agree that it's an example of something it may be worth trying
to optimize for.

You mention that you saw tgid exits - what order did the individual
threads exit in? If we threw the mm to the last thread in the thread
group rather than the first, would that help?
