Support running in background thread

Is there a way to run this as a background thread? I tried something like this:

def runUI():
    from asciimatics.screen import Screen
    Screen.wrapper(statusUI)    

def statusUI(screen):
    screen.clear()
    (height, width) = screen.dimensions
    while True:
        # ...
        screen.refresh()
        sleep(1)

from threading import Thread
thread = Thread(target=runUI)
thread.start()

but encounter an error when running: ValueError: signal only works in main thread

(sorry if this is abusing the GH issue channel – It is partially a support question and partially a feature request)

Am I missing something, but can’t you just construct the Screen on your main thread using the open() method and then run it from your background thread?

Good! I assume that’s all you need now… Feel free to follow up if you need more.
