The problem is that there is no room for flags field in epoll_pwait1, which is
asked for, in previous discussion thread [1].

Ahh yes, I certainly should not have forgotten that. But that's easily solved.
Do as for pselect6():

strcut sigargs {
    const sigset_t *ss;
    size_t          ss_len; /* Size (in bytes) of object pointed
                               to by 'ss' */
}

epoll_pwait1(int epfd, struct epoll_event *events, int maxevents, 
             struct timespec *timeout, int clock_id, int flags,
             int timeout,
             const struct sigargs *sargs);

Alternatively, place the clock_id in the lower 16 bits of flags.
MAX_CLOCKS is 16 right now, so there's room.
