It is possible to lower the memory consumption (RSS) by calling malloc_trim(0)
from "gdb --pid $(pidof xfdesktop)" to free about 30 MB of memory (on a 4K
display) to get 117 MB RSS.

It might be the case that some of the trimmed 117 MB isn't returned to the
operating system because of memory fragmentation. I will try to determine
whether this is the case.
