This is indeed strange. When I replace the last line with a longer
output, i.e.

In [1]: icap('for i in xrange(10): print i') | idump
In [2]: icap('for i in xrange(10): print i') | ibrowse
In [3]: icap('for i in xrange(10): print i') | idump
In [3]: icap('for i in xrange(10000): print i') | ibrowse

I get the  staircase output starting with 9739, i.e.

...
9736
9737
9738
9739
    9740
        9741
            9742
                9743
                    9744
                        9745
                            9746
...

However I've changed your code a bit (see the attached updated version
of the patch), and the result doesn't have that problem (but don't ask
me why).

Servus,
