I wasn't happy with Alex's patch, and i suggested a different approach.  Eventually,
my alternate patch was tested, but I havent yet had a chance to commit it to the
repositories. Thank you for this reminder -- I will take care of this within the next
few days, hopefully we'll see it in 2.6.21.

As for 2.6.20, I will try to have the patch added to 2.6.20.1 or 2.6.20.2

Cheers,
