I'm signed up to the BUILD_SUCCESS notification, but there's been times
where they never showed up, probably due to the issues you mentioned.
What would be really useful, is just a status page of what commit has
been pulled into testing, and if it finished successful or not. It
doesn't need to display anything else but where it is in the test.

For example, if there's a web page of my git repo, I could see:

 branch ftrace commit SHA1-A - finished failed
 branch ftrace commit SHA1-B - finished success
 branch ftrace commit SHA1-C - running

Something like that, where I can see that your tests have picked up my
lasted push, and if I should be waiting for an email notification or
not.

Make sense?
