Comment 27 for bug 932088

We just had a case of 10+ broken builds slave being started up in short time. Typical Jenkins instance init log:

https://ci.linaro.org/jenkins/computer/i-185d097f/log

As you can see, "Acquire::http::Pipeline-Depth 0;" is set, but still there's hashsum mismatch error (but the fact that dozen of slaves was started up in succession may mean there' actually mismatch in the source).
