Well, I was simply following Anthony's advice from "[PATCH] #include cleanlines" : "The idea behind qemu-common.h is to avoid direct includes to help with portability." Alexandre

Thanks Stefan, Should I send a follow-up patch to remove signal.h wherever qemu-common.h is already included?

I didn't know that qemu-common.h pulls in system headers so users don't need to, I always figured .c files should include what they use. But if we use this approach we might as well update the codebase. Stefan
