But HDF5 is a big dependency -- it can be a pain to build. IT's great
for what it does well, and great for interchanging data with other
systems that use it, but if all you need to do is save and reload
arrays, it's pretty heavy weight -- that's why save and savez were
written.

It looks like the python zipfile module supports adding to existing
zip files, to It should be pretty easy to add this functionality to
savez (and savez_compressed) pretty cleanly.

I'll bet a patch would be accepted!
