The reason for SINGLE_MEMORY_CHUNK depending on NEED_MULTIPLE_NODES is
historic due to the way it is implemented.
I played with it this weekend and I got a working version of FLATMEM,
which can replace SINGLE_MEMORY_CHUNK.

I'll clean it up and send a patch later this week. A possible next
step might be to replace DISCONTIGMEM with SPARSEMEM (since
DISCONTIGMEM has been deprecated).

Kind regards,

Kars.
