Thanks very much for the response, Todd.  This is very helpful.

I'm curious what type of information it would make sense to
make a separate interface for, rather than just using printks
for these.  Is this just to simplify parsing after the fact,
or would there be some kind of extraction/filtering API as well?
Do you have an example of the type of data that would be
saved this way?

Also, have you considered putting the logs into this kind of
persistent buffer?  I think Brian mentioned something about
a feature to make the logger buffers persistent.

Thanks,
