They do this with GCC, and Mark Mitchell has credited it with improved release
speed and quality. When something breaks, everyone who has checked in some
code since the last successful test run gets a complaining e-mail every day
until it gets fixed.

Do these failures typically result in a huge number of problems? Perhaps a
simple threshold, such as "if there are more than X new failures, e-mail the
maintainer of the tests; otherwise, email the people that checked in code

The advantage of automatically-generated e-mails is that they would come
quickly. For instance, I broken function on GCC 2.95.3 two days ago. I'd
looked at a few (but not all) regression results, and hadn't seen any
problems, so I forgot about it. Had it not been for David A. telling me
directly that I broke something, I would not have known until a release came
up and people started looking at regression results more carefully. It's much
easier to fix code when you write it the first time, instead of months later
in a time crunch. Automatically-generated emails can help that.
