), there is a memory leak in xfce. 

How to reproduce: leave an Xfce session for several days (7--10 days).

Result: the physical memory (256Mb) is full, the swap is almost full. After exiting Xfce, and logging in through xdm again, the memory is almost free (is used just a little).

Expected: memory doesn't leak.
