Why is it undesirable to have ncurses?

It is usually a shared library, which is not too large, and
pretty probably already mapped to some process in the system
(132772 bytes in Ubuntu 12.04).

Please remember that in a demand-paged virtual memory system,
the memory allocation is in the address space of the process
only. The real RAM chips get only used when a page is accessed.
The extra functions do not load the memory capacity, except
in the file system.
