Note that I still agree with Ruslan's comments to your patch, use 
of ngx_socket_errno to check errors from ioctl() / fcntl() in 
unix-specific code looks unneeded.  And in case of eventfd - it 
looks certainly wrong, as eventfd isn't a socket.

I would rather drop most of the src/os/unix changes, probably with 
the exception of ngx_tcp_nopush() checks.
