What kind of speedup do these builds get from ccache?
Still sort of curious about the actual measured speed benefits of ccache for these builds, what with the fact that my reported number of failures has to be somewhere between one third and one tenth of the total number of failures.

Chris, this is a frequent source of wasted build time. Can we please find an owner?

FYI, we may be replacing ccache with glandium's S3 cache soon, see
