    fix: Log panel busy wait during curses lock
    
    If we registered events while the curses lock was held (for instance with a
    popup or prompt for user input) then arm would peg the cpu. The reason for
    this was that the log panel was attempting to redraw itself, but not
    registering any of the attempts since they all failed so it became a busy
    wait.
