lightdm uses ~30 Mb of RAM

Bug description:
After loging in into the XCFE environment, I open a terminal and
perform a top.
If I sort the processes by decreasing resident memory, I see that
lightdm requires 32MB of memory, that is more than X !
Since lightdm just sleeps after login in, I think it is wasting
memory.
Could it possibly load/unload features dynamically as gdm already did
(many small processes which were launched when a feature was required)
?
