That deletes everything, but really I just want to hide the current prompt. So say this is how the console looks:
```` julia> println(5) 5 julia>function foo(x) println(x) ```` So in this case the users is in the middle of entering something new into the REPL (i.e. the definition of foo). Assume that at this point my background task receives a message. I then want to be able to delete line 3+5, and position the cursor on column 1 line 3. Then I’ll execute the code that was sent to the server. Once that is finished, I want to print line 3+4, as it was before I hid the current prompt, again, starting at whatever the current cursor position is. For example, say the background task received some code that printed “Foooooo” to the console, then I want the console to look like this, immediately after that code was executed: ```` julia> println(5) 5 Foooooo julia>function foo(x) println(x) ```` I.e. the user could continue editing the stuff that he/she was working on before the background task briefly took over.

Then include a file that will start a server listening on some socket. This server is all async, so as soon as the server is started, the prompt appears again and one can use this REPL window in the normal way. Now some other process connects to the socket, and sends some code that this server will eval. Before the server evals this code, I would like it to switch off the prompt, then eval the code, then switch the prompt on again. Base.Terminals.clear(Base.active_repl.t); sleep(10) will clear the REPL window (including prompt) for 10 seconds. Instead of sleep(10), you can do wait(c) where c is a Condition variable that gets notified by the server thread once it is ready.
