Why do you think so? listen sockets have some backlog, so concurrent
requests are not lost but are "buffered" and processed later.
It might be bad performance-wise, but otherwise it is ok.

There is a significant inconvenience that one cannot have both REPL and
server running (without some trickery, at least), so development/debugging
won't be pleasant at all, but it is doable at least.
