You are probably going to have to use ccall anyway to do things like save state. Only a limited set of system calls are available to signal handlers, see http://man7.org/linux/man-pages/man7/signal.7.html, and you can't rely on normal Julia IO to only use the allowed ones. Same for anything else that uses system calls.
