Description

"src/foo/core.cljs"
(println "hello")

Sometimes this works:

$ clj -Srepro -m cljs.main src/foo/core.cljs
Compiling client js ...
Serving HTTP on localhost port 9000
Listening for browser REPL connect ...
hello

and other times it doesn't:

$ clj -Srepro -m cljs.main src/foo/core.cljs
Compiling client js ...
Serving HTTP on localhost port 9000
Listening for browser REPL connect ...

and when it fails the browser will log

[Log] Could not send {:type :print, :content "\"hello\"", :order 8} after 10 attempts. (repl, line 3272)
[Log] Could not send {:type :print, :content "\"\\n\"", :order 9} after 10 attempts. (repl, line 3272)

making it appear that the REPL terminal is shutting down before the browser can flush its prints.

This seems very much related to CLJS-2574.
