gtype can give you the memory allocated by the object _structure_, but
not by the object fields. i.e. i'd expect most memopry usage to steam
from strings/byte-buffers etc. being maintained by an object, rather
than the object's pure structure size, which is why i suspect that gtype
profiling won't give you too much of an idea on where most memory
consumption occours.
