Clearly.  A cronjob I made to echo to the stdout every minute on both 
the master and the slave causes instant death to replication.  I don't 
have to wait until tomorrow morning to find out.

I am going to find a way to pipe locally generated mail to a process 
that smarthosts/mailhubs to the master.   Hopefully someday cyrus will 
be able to handle inbound emails on replicated systems, as well as 
pop3/imap traffic.  The world would be ideal :)
