Benno,
if i remember correctly the swap-on-raid problem was a memory starvation
problem between the raid code needing memory for computations,
so the system swaps out pages to disk, leading to the raid system
needing memory, and so on. I don't believe that swapping to a file
on an md device can do anithing to better this condition.
I believe a solution might be reserving enough pages in kernel memory
to handle raid, can this need be calculated????

Luca
