Yes, that can happen, I have an eye on such situations as well, but I
don't add all those cases to rezgbot, as some of them get quickly
resolved in a day or two. But you are totally free to get regzbot
involved if you want!

No, sorry, please don't read my reply like that. Feel free to tell
regzbot about such cases. But you could do me a favor in cases that are
similar like this: when adding the issue to the tracking use "#regzbot
monitor <url>" to point to the fix and "#regzbot fix <subject>" to
mention its subject, as that makes it clear that a fix is under review
and/or incoming; and when it landed regzbot will automatically consider
the regressions resolved, too.

That's up to Linus, but I guess he and others that got your report all
receive enough mail already; so if you ask me, for issues that are known
and handled already I'd say its best to send them just to the regression
list while making it obvious that a fix is in the works (see above); if
things are not resolved more people can be brought in later. But that's
just how I would handle it.
Ciao, Thorsten
