persistent factory map fails random io test

[jurgenvinju]

Deep random value failed, now trying to find the simplest sub-term which causes the failure...
Test fail:

the only difference seems to be the order of the map entries. could indicate a hash collision and a failure to deal with this properly.

Actually it has more than one collisions!?
