Proposal: SQL Query Scheduling

I've only been here for a few days, and I have already noticed a  
large issue with users running queries that may take several hours,  
without any notification to other users of the tools server, often  
resulting in replication lag. While notifying the users of the tools  
server will not exactly be a big help, a query that is intended to  
take up a large chunk of time could be shown to users of the tool  
server for help with any possible optimizations that may result in  
speed increases with your query. As well, a query can be  
strategically placed to run at times when the tool server is at low  
activity (possibly during the night.)

Just a thought.
