As long as the actual frequency is low, the number of users should be
okay. Okay, just one more question before adding it to todo list. Do
you think it would really benefit from scalability provided by
multiple workers?

* Do machines ever report that many MCE errors? The usual rate seems
like one per weeks or months even when they're frequent.

* If a machine is actually reporting enough errors to overwhelm single
error handling thread, does it even matter what we do?

Thanks.
