+Subject: [PATCH] Buffer OOB setBlock calls
+
+lets debug mode throw a trace in order to potentially see where
+such calls are cascading from easier, but, generally, if you see one setBlock
+call, you're gonna see more, and this just potentially causes a flood of logs
+which can cause issues for slower terminals, etc.
+
+We can limit the flood by just allowing one for a single gen region,
+we'll also only gen a trace for the first one, I see no real pressing need
+to generate more, given that that would *massively* negate this patch otherwise
