Stupid question: 6.0b1 LORs - who wants 'em?

[Marc Ramirez]

I'm running 6.0-BETA1 to help out the effort, and I got a lock order
reversal.  I assume I'll get more.

Should I be filing PRs for these?  Posting them here?

Is there better debugging info I can turn on?

Which is better, salmon or tuna?
