Unpopularity of global variables - why?

I haven't used custom props much yet, but I do think that locking messages is something that should be used sparsely. There are times when it seems it's the only way around a prickly problem, but I suspect some of those situations could have been also solved by a design change. Once painted into a corner, locking messages may be the quickest way out. Normally it shouldn't be necessary. I try to design my interface so that I let the engine do what it was designed to do. 

I'd be curious if people can summarize all the times that locking messages became a necessity, and then see if some of us can figure out "another way of going about it".
