I think you are misunderstanding what I said. You are taking things out of context. I was saying here what I did was inspired by why the syscall was designed to begin with. The syscall below refers to epoll_wait and not epoll_pwait.

and even this part of your email is very confusing. because in this case we can never miss a signal. I'd say
1. block the signals you don't care about 2. unblock the signals which should interrupt the syscall below 3. syscall() 4. block the signals unblocked in 2.
