   *
   * stdio (via open_memstream) is used for all vector management,
   * thus everything is a `FILE *'
+ *
+ * Buffering is naive: write in full to a memstream to get an accurate
+ * Content-Length, then write out the header and sendmsg it off.
+ * I'm avoiding a streaming + lazy buffering design based on fopencookie(3)
+ * since that adds more complexity and uses icache.
+ * Supporting gzip would be nice, but linking zlib is not an option since
+ * there's a risk of conflicts if the application links against a different
+ * zlib version.  posix_spawn+gzip isn't an option, either, since we don't
+ * want to generate intrusive SIGCHLD.
