Hi Andreas,

This patch looks like a great idea and a clean implementation.  Thanks
for sharing.  Would you be willing to sign the FSF copyright assignment
papers?  If not I probably can not apply your patch as it changes over
10 lines -- which I'm pretty sure is the copyright assignment cutoff.

Thanks! -- Eric
