(Whiteboard: [kanban:engops:https://mozilla.kanbanize.com/ctrl_board/6/919] ) 

We know populating the tags cache is one of the sources of try scalability problems, especially where ctrl+c is involved.

IMO tags have little to no value on the try repository. I think writing an extension that short-circuits the loading of tags and populating the tags cache would help with scalability until Mercurial handles the situation better.

This is probably a 10-20 line extension that monkeypatches a function or two in mercurial/tags.py to no-op.

If this is deployed, I think we'd still have the branch cache to worry about. But at least we're in a better position.
