RESOLVE MAJOR BOTTOLNECK (and even bugs) of banana :

building the Whole spool for xorg.promo.2002 with more than 1800 posts takes less than 3 secs !!!
the 2 array_map of the headerDecode function took more than 11secs before to do their job (for the both)
---> now it takes less than the second !

oh yeah !
