If people don't monitor the buildfarm then it isn't serving its purpose
of catching these things quickly. To aid that process I am currently
working on a notification enhancement for buildfarm which has long been
requested. Here's the description I sent to the buildfarm list (the
first few lines refer to how buildfarm members would have themselves
notified - non-buildfarm members can ignore):

The enhancement is almost done, and the whole thing will be complete
this weekend, I hope.

The mailing lists are being set up as digest-only, at least for the all
and failures lists - the state change lists should have much lower
volume, and I will probably make them digest optional.

comments welcome (buildfarm exists to help people on this list - if you
want something speak up).

cheers
