Talking to Spamassassin's spamd. The way the client specifies that it is done 
sending a message to the daemon is by closing the connection for writing.  
(see http://www.spamassassin.org/full/2.5x/dist/spamd/README.spamd for 
protocol details).

In this case I was able to easily work around the issue by adding an "End Of 
Message" command to spamd (gotta love open source).
