So this is a tree where you already _have_ most of the tags, no?

Can you add a printout to show what the "taglist" is for you in git-fetch.sh (just before the thing that does that

	fetch_main "$taglist"

thing?). It _should_ have pruned out all the tags you already have.

Or is it just the "git-ls-remote" that takes forever? (Or, if you run "top", is there something that is an obviously heavy operation on the client side?)
