On 32 bit systems the per process limit is usually 2 GiB, no matter how
much physical and virtual memory you have.

And with 2 GiB and 400000 objects you have about 5 KiB per object.  If
you pickle that huge list there has to be enough memory to hold the
pickled data in memory before it is written to disk.
