There is some psychology involved here. I see 26 patches and decide i
need to allocate 30 minutes to this sometime, and put the review off
until later, without even looking at them. If i get 5 patches, i
probably just do it, knowing i will be finished pretty quickly. My
guess is, 5 patches a day for 5 days will be merged faster than 26
patches in one go.
