Running bulk again had no troubles, no use of MAKE_JOBS_UNSAFE
involved.

However, I use poudriere with ALLOW_MAKE_JOBS=yes and do not
restrict PARALLEL_JOBS. The first run had 4 builders running
(one per core), each allowed 4 active processes. The 2nd run
had only one builder active while building nss simply because
everything not dependent on nss had been built already.

The 4-builders, each allowed 4 active processes, apparently
makes it more likely to fail the race condition.
