[BUG] Help output is printed slowly about septum HOT 6 OPEN

Thanks! I'll look when I can, but it might be a couple of days before I get to this.

Might be a regression of #35, I think it might be buffering due to not using a back buffer and the current Trendy Terminal newline settings instead of scrolling. Last time IIRC it was related to a long delay due to VT100.Report_Cursor_Position procedure.

Using https://github.com/onox/goblin-terminal (it uses VTE like gnome-terminal). But output is printed instant in tmux! 😮

Yup, if you use strace to check the length of the system calls you might see an issue. htop has an easy way of doing this.

For each line printed, I see:

• read()
• read() returning E_AGAIN
• write()
• 4x poll()
• write()
• clock_nanosleep()
• 2x poll()
• write()

With weston-terminal the output is printed instantly and I see:

• epoll_wait()
• read()
• write()

Slow in gnome-terminal as well (not a surprise since it uses VTE)
