For -rc/-stable patches, avoid queueing. If you have a patch, post it
to the maintainers ASAP. It then becomes our problem (and a smaller
problem too, since the less delays there are, the bigger the chances of
making the intended release). A few days are fine of course.

For mainstream patches, queuing is fine, but don't overdo it please. I
enjoy pulling from you and am quite willing to pull several times per cycle.
