You mean the data (n bytes) is actually sent by machineA and also 
received by machineB but NSFileHandleReadCompletionNotification is not 
posted until at least N (N > n) bytes have been received?

If anyhow possible I would like to use the NSFileHandle notification 
mechanism versus polling for available data.

Can the timeout be reduced?

Thanks!
