Ha!  They didn’t regress for me.  I validated before committing.  How strange.

I agree about keeping it green

These were regressions from your simplifier refactoring. Yes, we should 
investigate. I'll open a ticket this evening, unless someone else gets to it 
first. But we surely don't want to keep CI red on every commit until then.

David, are you sure we want to accept a more than 5% increase in compile time 
without investigation?   What commit caused these increases?  Maybe they are 
readily squashed? Generally we are trying to improve compiler perf not accept 
it getting worse!

This is moderately likely to be common: many people incorrectly believe the
lock manager is a server-only daemon, and reliance on file locking is
uncommon enough that they are rarely disabused of this belief.

Command 'rpcinfo' is available in '/usr/sbin/rpcinfo'
The command could not be located because '/usr/sbin' is not included in the

This is most likely caused by the lack of administrative privileges associated
