and just for reference, with the recent fetcher improvements:

real	113m39.607s
user	458m25.570s
sys	55m15.250s

I'm doubting the accuracy of the user figure there but the build should
be faster overall due to less taring/untaring of tarballs and it looks
like it is. It would be possible to really show an improvement by
specifically profiling the kernel/linux-libc-headers recipes.

Cheers,

Richard
