Code review comment for ~dirk.zimoch/epics-base:FilterForInfoFields

> I'm not sure this is necessarily always true. I've been toying with the idea of involving db_field_log in reference counting where a record and and some db_field_log would share ownership. I haven't completely worked this through.

I think I agree. This is why I proposed to allow the filter to override the conditional with an explicit "this is mine, keep off" bit.
