Memory consumption with glibc malloc and jeMalloc (straight line).

We now changed to another malloc implementation: jeMalloc
(http://www.canonware.com/jemalloc/) which is a magnitude superior to the glibc
malloc. A similar implementation is also used in *BSD variants!
Linux/glibc should really improve their malloc since the current implementation
is not sufficient for large applications. 
Why can't this implemenetion be used inside glibc? Is it GPL <-> BSD license
problem?
