Yeah - as long as it does not pull in too many non-fix bits it should be
OK and should be (much) easier to handle than trying to create something
stable-only.
Size of a fixes queue shouldn't be an issue as long it works and as long
as it's not excessive - this was a truly difficult problem and you did a
nice job of mapping it out and fixing it for good. 7 fixes is what it
took.
Thanks,
