I just checked the implementation and it uses ''.join combined with some bogo-optimizations to cache the result of the join when you do a seek or write. That is, .seek can take linear time instead of constant time, a pretty bogus situation if you ask me, though maybe the amortized time isn't so bad over multiple calls. I didn't check how cStringIO does it. -- http://mail.python.org/mailman/listinfo/python-list
