And here's the simplest scheme: you don't extend the buffer. On
overflow, you say "Buffer full, here's the MCE" and you dump the error
long into dmesg. Problem solved.

A slicker deduplication scheme would be even better, tho. Maybe struct
mce.count which gets incremented instead of adding the error record to
the buffer again. And so on...
