This is something that I wanted to do right after getting
rid of all crashes. Unfortunately that keept me busy since
two weeks, now, and I'm still hunting one special case.

Adding this pickle support should not be too hard and quite
straight forward. Have a look at prickelpit.c where almost
all pickling code lives. There is some support that allows
to patch the type objects and method tables without patching
their source code at all, which I prefer, to keep the number of
patched files as small as possible. (I'm trying to reduce these,
further).  I guess it would be possible to create a few generic
functions for all iterators and control them via format strings,
since they are very similar?
