---------------------------------------------------------------------------

Also, why is it fine to exclude errors by default and not on per case basis? 
Why do DSE popped up? I think I have to do one more pass on this tomorrow 
carefully.

And again, if the original patch exposed more unrelated bugs, I don’t expect 
all of them to be fixed in one ticket. If additional tickets are needed and 
more work and attention - I am fine with that.
