Comment (by nickm):

 b) I think that if this does turn out to be ignorable, we can downrate it
 even further.

 c) Hm. I don't have a great justification.  For any good N, N/2 and N*2
 are probably good choices too.  Basically, I wanted a number that wasn't
 too high, but which still gave a pretty small chance of failure when the
 space started to fill up.  For N=64, there's a one-in-a-million failure
 chance when the space is 80% full, and a one-in-850 chance when the space
 is 90% full, and a one-in-26 chance when the space is 95% full.  That
 seemed okay.

 d) So as to avoid spamming the log with junk.  I guess we could refine it
 to rate-limit it per channel.

 ra, are you able to test this patch over the weekend?  I'd like to know
 what kind of results it reports, and whether it indicates a possible bug
 in the #7351 code.
