 From what I understood from him, this had a lot to do with the "epoll" 
change I investigated some time back. I'll let Mike say whether that is so.

If it was, it was merely the time it takes to copy the list of file 
descriptors to check into kernel space, and the list of modified 
descriptors back. I've had a client with this problem a while back.
