[Message part 1 (text/plain, inline)]

By the way, today Emacs 29 hung in Magit blaming for me, with C-g doing
nothing. Grepping Magit sources suggest it uses the "save-restriction -
temporarily widen" more than ten times in various places, 3 of them when
blaming. Cannot say for sure that was it, but all the outer symptoms are
identical with the hangs in Logview.

I really think there must be a way to "widen no matter which locks are
installed" - a lot of code seems to depend on that.
