Sorry for the high level of noise...

I profited by the low traffic to apply Eliot mechanised tool (
http://www.mirandabanda.org/cogblog/2008/11/14/mechanised-modifications-and-miscellaneous-measurements
)
+ own manual changes to remove as much writes as possible (in a short
time frame) to remote (external scope) temporaries from within a
closure.
This should fast up a little bit the image (probably not that much
until Cog is available).

We shall now take the habit of declaring temps in inner scope possible
and avoid writing in outer temps if possible.
By now, the cosmetic changes has at least a virtue of serving as examples...

Cheers
