No idea why _I_ didn't think about this solution. :-) Right, that should
solve it.

Another idea is to run several concurrent scripts. Except for the final
packing, the target builds are completely independent.

Only the final libs and binaries are copied at the end of each
successful build. The objects are never moved.

I'm currently trying to add some timing output to the scripts in order
to get more precise figures.

Regarding SSD: I found several articles of people complaining about
marginal performance gains when compiling on certain SSD. For example
Google for "C300 128GB looks good on benchmark".

Thanks,
