It would, if it were a static library.
Not so with a shared library. With one, you have a binary option: either
you load it entirely to memory, or you don't load it at all.
Luckily, libglib.so is quite small (150k in my system). Besides, libstdc++
also duplicates many functionalities that QtCore provides and we're
forced to load it as well (and it's 830k here).
So, in all, I'd say it's worth it.
