No, not really. If a page has not been faulted in, it hasn't been mapped 
to physical memory yet and does not occupy buffers or cache (it may 
already be in cache, but that's another story).

According to the headers in libglib.so, it has a total virtual memory size 
of 149544 bytes, of which only 1828 are non-sharable -- or exactly one 
page.

I would compare to QtCore if I could, but I don't have a non-debugging 
non-exception build available. (just for info, my libQtCore_debug.so has 
230394 bytes of exception headers and tables alone)
