For the sake of justifying this as "fix" rather than "cleanup", you may 
as well use the flush queue commit cited in the patch log - I maintain 
there's nothing technically wrong with that commit itself, but it is the 
point at which the underlying issue becomes worth fixing due to how they 
interact ;)

Cheers,
Robin.
