 OK, I did that.
 
 Mark, can you add this to your watch-list? My gut tells me that we will 
 get _lots_ of PRs from this one otherwise. Jason's got a tentative patch, 
 so we might have a resolution there soon.
 
 Jason, can you make sure this goes into 3.3 as well if the patch works 
 and Mark agrees?
 
 W.
