This seems reasonable. maybe listen_qlen_ would be be better, but it
is fine as is.

zero is better -- default behavior is "believe the application". Matt
indicated D.U. works this way (with a default of zero), and it seems
reasonable to me. If you want to forceably raise it because you have a
specific application that isn't performing well, then you can. "We
supply the rope..."

Hmmm. Not sure we want to force things to be done that way.

I agree with all the other things said that I didn't specifically
comment on.
