Actually, I'm not sure that the vger version had the locking exactly
right before.  The version in vger is now the same as the version
currently in the official tree, and I am moderately confident it's OK.
If you can reproduce it with that version, I really will have to dig
deeper.

We will never get the sd.c patch into the official version because it
breaks SMP machines.  I know because that's what happened on my SMP
powermac. :-)
