That makes sense, indeed.

Yes, usually it's very quick.  But when it's not (e.g. manpage on
a remote server that's temporarily down), it hurts.

As you say, when it's very quick, there's no point running the process
asynchronously, and neither is it useful to only display the buffer
after the rendering is done.

The FreeDOS build of Emacs doesn't support start-process (because
FreeDOS doesn't support multiprocessing).
