Anything calling poll() on 1000 fds probably has performance
issues already! Which is why kevent schemes have been added.
At least the Linux code doesn't use a linked list for
the fd -> 'struct file' map which made poll() O(n^2),
and getting to that number of open fds O(n^3) on
some versions of SVR4.
