Hi Detlev,

It looks like this one slipped through the cracks. I've looked through 
my e-mails and found one from Wolfgang on 6/8 where he said he'd apply 
it, so I acked the patch rather than pulling it myself. For whatever 
reason, it didn't make it in.

I've rejigged the patch to apply to TOT, and have applied to the net 
repo. Please find the fixed-up patch attached, as applied to 
e99e9575bbeba1b7c48e046547cae065ec0071de
