NAK to the entry changes. That code you’re changing is already known
to be a bit buggy, and it’s spaghetti. PeterZ and I are gradually
working on fixing some bugs and C-ifying it. ASI can go on top.
Agree this is spaghetti and I will be happy to move ASI on top. I will keep
an eye for your changes, and I will change the ASI code accordingly.
Thanks,
