Should this be on the blocker list for the 7.10 release?

It seems to fix most of it.  The only odd thing left that I
noticed is that it leaves some of the inferiors there.  When I
type "info inferiors" after running the program, I see one or
two of them left.  I believe there should only be inferior #1
left.

I haven't, but I will.

Thanks!
