As for me, the main use of "Expect: continue/100 Continue" dialog is
the request body limitation. I had even written article (sorry, in Russian)
"Why it's impossible to limit correctly the uploaded file size":

The problem is that browsers do not read server response until they
will send whole request body. If server will close connection before they 
have sent body, the browsers issue some network or common error,
that has no relation to the "413 Request Entity Too Large" error.
