I think this bug is to do with lack of handling for ANSI escape sequences. I'm currently looking into it.

OK, the reason for this bug is that by default in the ncurses library the environment variable ESCDELAY pauses the execution to way for functional key sequences. the default value is 1000ms thus the second's worth of pause. The way round this seems to be modifying the os.environ['ESCDELAY'] variable during runtime execution. I haven't found any documentation on how this would be achived however..
