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
