Have you made any progress in further identifying or narrowing down
these bugs? Detailed bug reports or, better, patches, are always more
useful than general reports of issues.

We've not seen any bugs ourselves but obviously if it's biting you
regularly then may be worth while disabling in your config. I'm
loathe to disable it by default in the general config since this
won't help us uncover and fix whatever bugs are present.

Sure, good point (though as mentioned above, we hadn't seen any
problems ourselves -- we strongly appreciate the community effort
in helping us ensure new changes work on a broad range of configs
and usage scenarios).
cheers,
