SYNOPSIS

       #include <sys/epoll.h>

       int epoll_pwait1(int epfd, int flags,
                        struct epoll_event *events,
                        int maxevents,
                        struct epoll_wait_params *params);

Quick, possibly dumb question: might it make sense to also pass in 
sizeof(struct epoll_wait_params)?  That way, when somebody wants to add
another parameter in the future, the kernel can tell which version is in
use and they won't have to do an epoll_pwait2()?

Flags can be used for that, if the change is not radically different.
