You can be developing other tools. My builds oftentimes take a long time because there are a lot of cross-language stuff (libraries include some boost stuff, which always takes a long time to process) and cross-compiling (e.g. targeting tools for osx and for linux -- why they changed the syscall numbers is beyond me) You probably have a laundry list of scripts that should exist (e.g. launch scripts, cron jobs, etc) but are low-priority. It's easy to work a little bit on a script when building.
