The solution is technically easy, I guess we just need to decide a
policy. I'd implemented the current one thinking it was a good
balance between seeing displayhook output in the most common cases and
not getting multiple ones otherwise. But we can certainly revisit
And we could go back to always compiling in single mode, if we want.
Though that would trigger multiple Out results when running calls
like matplotlib plots, that are intended for their side effects but
still return a value. That was a big driver of deciding to silence
