I guess this is related to the general linux design - every block device
has to have an I/O queue - and I think each process represent such a
queue in this case. I am not 100% sure it is the sanest setup for
mtdblock, may be yes, may be not, needs thinking.

But in general note, mtdblock stuff needs a lot of love.
