I agree, I probably shouldn't be putting speculation in the log
messages. I'll change this for the next reroll.

I'll probably keep the patch text, however. In the previous version, we
were implicitly relying on the value of THREAD_SHALLOW to be 1. This
seems a little bit flimsy to me since it's possible that the enum can be
changed in the future and it may invalidate that assumption.

I'll keep it explicit so that it's a little bit more robust and also, so
that it's more obvious to future readers what's going on.

Thanks,

Denton
