I only put it in drbd07 to ease propagation with svnp.
and so it does not get lost.

currently I go over all those small patches I sent somewhen and never
got any reaction about, and just remove them if they meanwhile are no
longer usefull, or apply them if I think they could do something good.

I do not know.

it is #if 0'ed in drbd 0.7
I think we should #if 1 it in trunk,
benchmark it, and drop it if it does not do any good.
