First instant goes from 7 MB to 22 MB (15 MB more than it would without
arrows), each additional instance shows 22 MB but only decreases free memory by
12 MB (5 MB more than it would without arrows). I use urxvt because it has a
smaller footprint than other terminals (like nano vs other editors). It has a
server/client mode similar to what you describe with xfce terminal, but if any
instance were to crash, they would all die.
Greek and various math symbols only increase urxvt from 7 to 10 MB. So even
someone using normal unicode text might see an increase with the arrows.
I can patch out the arrows if I decide I'd rather have an extra 300 MB of
memory. But anyone else using a small terminal would have to live with the
larger size. Any of them who opens nano's help will already see increased urxvt
usage until they close that terminal.
