Hi Matthias,

Fair enough.  I suppose my best bet then is to either add other exact
output (output will be consistent, but different from lossless stores)
or skip tests that make non sense for this backend.

Maybe I shouldn't have mentioned it yet, the "brooding" is still going
on.  I need to think a bit more first.

I allocate a fixed number of slots and use a hash to decide where each
word goes.  This leads to slots being occupied by multiple words which
can disturb the perfect outcome.
