Well, even for circumstances other than authentication, there is nothing we 
can really do about an ioslave that is already in the middle of processing a 
request. We just want to ensure that it gets updated for the next request, 
that includes the ioslave that originally sent the internal meta-data.

For authentication this is actually not an issue because not only do you have 
to wait for user input as you stated, but also subsequent requests into the 
protected site are completely dependent about the first request. IOW, if you do 
not get the first page, well you cannot parse it and make other requests.

Indeed... it is a possibility. Fixed...
