hum.... i'm a bit confused now.... reading the revision patch..

http://bazaar.launchpad.net/~maria-captains/maria/5.5/revision/3888#extra/jemalloc/VERSION
3.3.1-0-g9ef9d9e8c271cdf14f664b871a8f98c827714784

why 3.3.1 if 3.1.0 should be better?

>     [merge] Tue 2013-09-10 23:02:25 +0200
>       - merge with 5.5-tokudb tree (TokuDB 7.0.4). In particular:
>          - add TokuDB, together with the ft-index library
>          - cmake support, auto-detecting whether tokudb can be built
>          - fix packaging - tokudb-engine.rpm, deb
>          - remove PBXT
>          - add jemalloc   (no information about version here)
>          - the server is built with jemalloc by default even if TokuDB is
>          not built   (no information about version here)
>          - documentation files in RPM are installed in the correct
>          location
>          - support for optional deb packages (tokudb has specific build
>          requirements)
>          - move plugins from mariadb-server deb to appropriate debs
>          (server/test/libmariadbclient)
>          - correct mariadb-test.deb to be not architecture-independent
>          - fix out-of-tree builds to never modify in-tree files
>          - new handler::prepare_index_scan() method
