Circle 2 is interesting but it's not my case, I do not costruct object
that way and fetch data from a postgres/postgis database.
Putting in the code lines such as
>cat('point 1 mem', memory.size(), memory.size(max=TRUE), 'nn')
doesn't help because those commands are windows specific and I work on linux.

Here follows a link to my script and RData, lines commented are not
needed because objects are in the RData
http://cen.isprambiente.it/~rmorelli/R/

I've just purged unusued objects from RData.
