Re: unwind-protect within while-no-input

[Spencer Baugh]

Put another way:

It seems like it's impossible right now to use unwind-protect robustly
in face of quits, because a quit triggered in the body forms of the
unwind-protect will also interrupt the unwind forms.

And there is no way to work around this, because binding inhibit-quit
in the unwind forms can *also* be interrupted.

Maybe there should be a version of unwind-protect which automatically
and atomically inhibits quit in the unwind forms?
