one can endlessly debate whether or not it's safe to use
NSOperationQueue or one can use it and ship a product a great deal

That's true. However, there are some surprisingly easy ways to end up
with multiple queues - one example might be if one queue is associated
with each document object in a document-based application. (In this
case, the bug might manifest as rare crashes when multiple documents
are open and "doing stuff".)
