I am fine with whatever fix for this you guys settle on :) Just for the 
record, I proposed this back then:

	http://lore.kernel.org/r/nycvar.YFH.7.76.1904151300160.9803@xxxxxxxxxxxxx

maybe it could be resurected, as I believe it'd fix this one as well?

But again, I have absolutely no preference either way, only that it'd be 
nice to have this fixed :)

Thanks!
