I'm not sure. I think it's all of the above.

That's a good point! But surprisingly, stripping the gimp-2.3 binary
and all the libraries in lib doesn't make much difference -- the
stripped 2.3 still takes 33M at startup.

Top showed:
             VIRT      RES         SHR         %MEM
gimp 2.3    56600      24m         10m         13.1
gimp 2.2    35984      20M        9.8m         11.2

I haven't tested in valgrind yet, or with G_SLICE=always-malloc,
but I'll do some more experimenting (probably not for a few days ...
I have some projects coming due).
