Pulled a new build on March 10, 2013, rebuilt, and reinstalled. No performance or UI problems were observed.

This is still a problem. I cleaned the workspace, pulled, rebuilt, and reinstalled (Jan 13, 2013). This time I typed in

> eps

and waited for about 1/2 hour. There did not seem to be a problem. After this wait, I attempted to enter

> 2

But, the ui was frozen. I hit "2" on the keyboard a couple of times. To unfreeze, I maximized the screen and then restored the size. The display read something like

> 222222222

Backspacing eight times, maximizing, restoring, and then entering a carriage return, maximizing and restoring, the console now reads
octave:1> eps
ans = 2.2204e-16
octave:2> 2
ans = 2
octave:3>
One of four CPUs is 100% active.

Do you still see this effect with recent dev versions?
