Just an idea: The only windowed applications I use are a terminal (st), my text editor (Atom), and a browser (Firefox). Suppose I switched to HyperTerm, Atom, and Chromium. I would have three copies of the Chromium renderer and V8 interpreter loaded in memory. Is there a project that merges these things into a single daemon, to improve individual app startup time, save memory, and reduce the binary size from 42 MB (for HyperTerm) to the size of only its own components?
