      Description

      I think we should switch the default for the IPC client and server NODELAY options to true. As wikipedia says:

      In general, since Nagle's algorithm is only a defense against careless applications, it will not benefit a carefully written application that takes proper care of buffering; the algorithm has either no effect, or negative effect on the application.

      Since our IPC layer is well contained and does its own buffering, we shouldn't be careless.
