I had some trouble reproducing it – because it only occurs in MS
Windows, where we need wrappers for some libc functions and
gwy_fprintf() was leaking the printed string (which is indeed a massive
leak).
It should be fixed in r22186, so also tomorrow's or later development
snapshot.

I do not understand the ‘2×2’ part. Are your images just 2×2, or you
want to create some block matrix structure, or...?
Anyway, you can do
data = datafield.get_data()
to get image data as a flat list and then write it to a file in any
shape or form you wish.
