It could be very quiet (i.e., machine runs with no errors) and it could
have bursts where it reports a large number of errors back-to-back
depending on access patterns, DIMM health, temperature, sea level and at
least a bunch more factors.

So I can imagine buffers filling up suddenly and fast, and userspace
having hard time consuming them in a timely manner.

Every byte counts in such cases.
