The repl runs fine, but when I try on the page, it hangs.

This project works as desired at, but when I try to run a hosted version at, it seems to start up, since it prints something out, but the "Repl Waking Up..." message goes on indefinitely.

This may be related to the fact that it uses character-mode i/o, rather than line-oriented. But it would be great if there were a way to make it work. (I have another project which uses Java Swing, but that hits another snag, and it is probably too much to ask to have that work.)
