Note: I'm not sure that "low CPU count" is the determining factor
(as in "the less CPUs, the worse"). Here are the updated failure
rates I'm getting with version 0.9.0-1:

(after testing 100 different times on each case).

On AWS machines with 1 CPU, it fails 18% of the time.
On AWS machines with 2 CPUs, it fails 92% of the time (so, not 100% as I
believed, but close).

I remember that version 0.8.1-1 used to fail a lot in both cases.

For 0.8.1-2 I don't keep any logs, as it used to build ok.

(Just for the record: I provided a VM to test as much as needed)

Thanks.
