Hi Don!

Thanks for your reply and the patch, my searches didn't turn up your 
post. Any idea if I'll run into trouble trying to apply this to 4.4.1? 
I'd like to stick with (minimally modified) distro packages if possible, 
and Debian Jessie is on 4.4.1. And any feeling for whether this will 
make it into 4.5? Sure would be nice to see this problem fixed for good.

Thanks again.

Steve
