Ehh, I'm not sure that's the case.

The back log only relates to connections that have not been picked up by 
user space yet. The above would be a rough estimate IF we can assume 
that all connections are very short lived in relation to the amount of 
time it takes to handle a connection and close it is very short in 
relation to the amount of time it takes between the connection being 
established and user space running "accept". Otherwise, netstat is of no 
help.
