It depends a bit on how you define things, but the answer you're
probably looking for is "either zero or one times".

When you load a shared library the memory actually used is shared not
just within the same process, but across all processes using that
library.  In all likelihood, some other process (like gnome-shell) is
already using Clutter and your program using Clutter doesn't require any
additional resources.
