(I observed > this with RPC server/clients) I have no technical objection to your patch, but I'm afraid you must be missing something, or else there is something special about the environment that you were measuring in. I have played with a few TCP-based Guile applications (including the Emacs debugging interface) and not noticed any obvious performance problem.
