Since first Lollypop version, I have reports about Lollypop high memory usage.

So I took time to test pixbuf loading and found really strange behaviours:

image_from_pixbuf.py

Here, we are loading a pixbuf and using Gtk.Image.new_from_pixbuf():

• While loading, memory usage goes to 600 Mio
• Floxbox is cleaned at the end and memory usage goes to 30 Mio

image_from_surface.py

Here, we are loading a surface from a pixbuf and using Gtk.Image.new_from_surface():

• While loading, memory usage goes to 900 Mio
• Floxbox is cleaned but memory is not freed

image_from_surface_signals.py

Here, we are loading a surface from a pixbuf and using Gtk.Image.new_from_surface() and signals to load images without freezing UI:

• While loading, memory usage goes to 900 Mio
• Floxbox is cleaned at the end and memory usage goes to 60 Mio

image_from_surface_idle_add.py

Variant of previous one using idle_add() instead of signals:

• While loading, memory usage goes to 600 Mio
• Floxbox is cleaned but memory is not freed

I'm really confused by all this strange behaviours.
