I can write a patch to do that for you.  However I'm more interested in 
solving the "infinite-retry" problem first.

I did write some patches which might help.  They weren't meant as bug 
fixes exactly, more as infrastructure cleanup.  But you ought to try 
them out, because they do affect the logic in this area.

The patches are here:

They are based on 2.6.27, not 2.6.28-rc.
