In an earlier blog post I wrote about a potential way of speeding up C++ compilations (or any language that has a big up-front cost). The basic idea is to have a process that reads in all stdlib header code that is suspended. Compilations are done by sending the actual source file + flags to this process, which then forks and resumes compilation. Basically this is a way to persist the state of the compiler without writing (or executing) a single line of serialization code.
