On some slow machines, like the virtual machine of Vista 64 and Windows 7, the ping always take more than 100 ms. And retrying 100 times the same operation is never a good idea. So i'm waiting 1 sec instead of 100ms, and i retry 10 times only.

And there was extranous err checks, I'm not sure why they were
there. Was there a line missing there?
