Super slow on AIX (draws 1 line per second) #607

Hi,

on AIX (ssh'd into AIX using iTerm 2), the drawing is super slow. 1 Line at a time is being drawn.

Here is an example from a mockup which prints processes (unfinished, only shows pid and user so far).

That was about 8 seconds after starting the process. This does not happen on Linux or Mac OS X. It is a little slow on AIX, too, but not that slow. Using text Graphics. Haven't tried "normal" text yet.

The reason is getting the terminal size. Calling it repeatedly will be extremely slow.
