That's interesting. I tried your program here and it works fine for
1024 fds, but fails for 1025.

If I become root, I can do:

constable:/home/john/try # ulimit -n 2048
constable:/home/john/try # ./a.out 2048
poll() returned 0

So I guess the problem must be in your glibc or your kernel. I'm
suse9.0, if that's any help (kernel 2.4.21, I think glibc 2.3.3)
