> Currently whenever an arena fills up to more than 256MB, a warning is issued with a stack trace. This is very common in the case of MRS arenas, which will often be larger than 256MB.
> The original intent of the warning was to catch cases where we were forgetting to Reset() an arena during a scan/compaction/etc. Given that, maybe we should be setting the "warning threshold" on a per-arena basis, or at least give the ability to suppress the warning for MRS/DMS where large arenas are the norm.
