And where do you draw the line? Do we expect ARM users to have 4GB of
RAM to compile phobos? Is 512MB enough? 64 MB? Even huge C++ codebases
such as GCC compile with 128MB memory.

I use docker hub to build docker images. One Dockerfile compiles one
small D tool which depends on vibe.d for JSON parsing. Without
separate compilation the build fails as docker hub kills the build
process, out of memory...
