Issue DM-1087: Research how to kill query in mysql
In the port to the new Xrootd Ssi API, worker-side squashing was lost in the shuffle. The plumbing is different, and re-implementing squash functionality is not entirely straightforward, especially because the new API is still missing documentation and examples for implementing cancellation. The consequences of not implementing this are minor--some extra work may be done by the worker, but not a whole lot, because user-level cancellation has not been implemented. First step is to understand how mysql code is handling query killing.
