It's a bit of a nit-pick, granted, but can we ensure that the count-down's remain padded/justified such that the numbers line up for easy at-a-glance inspection ? The optimal standard looks somewhat like the pre-merge Sizes: * Final size of build directory: 2696 KiB (2.6 MiB) * Final size of installed tree: 5372 KiB (5.2 MiB) Otherwise, I think this will be quite helpful.

[gentoo-portage-dev] [PATCH v3] collision_protect: use dynamic report interval
The reporting of files remaining can look somewhat odd since the report interval is hardcoded to be per 1000 objects. Adjust this interval to be time based. This means that modern (fast) machines likely will never see the countdown messages at all. On slow setups the message will be informative that there is progress, albeit rather slowly. While at it, report percentage done.

[gentoo-portage-dev] [PATCH] collision_protect: use dynamic report interval
The reporting of files remaining can look somewhat odd since the report interval is hardcoded to be per 1000 objects. Adjust this interval to be regular towards the end. While at it, report percentage done.
