/* The main process is the server process. It enters render_server_main and
* never returns except on fatal errors.
*
* The server process supports only one connection currently. It creates a
* render_client to manage the connection. There is a client process at the
* other end of the connection. When the client process requests a new
* context to be created, the server process creates a worker. It also sets
* up a socket pair, with one end owned by the worker and the other end sent
* to and owned by the client process.
*
* A worker can be a subprocess forked from the server process, or a thread
* created by the server process. When a worker is a subprocess, the
* subprocess returns from render_server_main and enters render_context_main.
*
* When a worker is a thread, the thread enters render_context_main directly
* from its start function. In this case, render_context_main must be
* thread-safe.
