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?

open file and set breakpoint causes CPU usage to go to 100%
