It might be a non-issue.) It's probably not an issue in practice, but it does seem rather unsatisfactory that we don't have a mechanism for doing tests for infloops in general. I wonder whether we could cobble up something just for ert. For instance... doing a (start-process ... "sleep 1; kill -s SIGUSR1 $EMACS_PID") or similar, and then hook the SIGUSR1 handler to... er... do something useful here. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
