Not sure about glibc emulating or what it means when you pass 255 to
epoll_create being emulated, but here's what the kernel does when you
call syscall epoll_create:

SYSCALL_DEFINE1(epoll_create, int, size)
{
        if (size <= 0)
                return -EINVAL;

        return sys_epoll_create1(0);
}

As you can see it translates to epoll_create1(0)

Sigh, yes-  I think i need to deal with forks explicitly. And for now
compile with glibc 2.8.
Thanks for your help.
