It takes virtually the same time  to start subsequent completions as the first
(building) one.

As an update,  on my Ubuntu Linux with emacs 23.1.1 and ESS 5.11 it takes about
1-2 sec to start a completion. I can leave with that. But anything more than 3
sec already interrupts the flow considerably.
