Hi Kasper:

Let's not argue about who killed who o:)  But, it is definitely a bug.
For example, if you had tried this in XEmacs, prior to the bug fix,
then you would have seen no hesitation.  That is about the only
advantage of the GNU Emacs vs. XEmacs split.  It is very easy
to see whether the problem is with ESS or emacs.
