Davide, I'm working on the signalfd(2) man page, and I've come acorss some puzzling behaviour... What are the intended semantics of a signalfd file descriptor after an execve()? As far as I can work out, after an execve() the file descriptor is still available, but reads from it always return 0, even if: a) there were signals pending before the execve(). However, sigpending() shows the signal as pending, and the signal can be accepted using sigwaitinfo(). b) we generate a signal after the execve(). Is this intended behavior (the "orphaned sighand" condition mentioned in the draft man page you sent me?)? Is it a bug?
