cool! I'm not currently working on any MPI projects, so I can't really test it
in-depth, but it seems to work fine with some of my old projects (which have
quite a bunch of assertions), too. But I guess that's not surprising given that
I used my version of that code before :)

I have a somewhat hacky thing that also forgoes serialization under some
circumstances (and thus isn't generally safe) in
but the *_serialize methods should be safe. I implemented them for gatherv and
allgatherv, due to the issues with archive sizes you mentioned I skipped
(all-)gather without the v.
