But I was just looking at the code to try to understand the previous backtrace. So, the "finish" stuff seemed to show that we weren't hanging in accept-process-output at all, but were instead just calling functions as normal, and looping on the Lisp level? And, for instance, Ffuncall has a maybe_quit, so C-g should work in these instances? But they don't, which is confusing. Is it even possible for the Lisp-ier functions in the backtrace to inhibit C-g? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
