This doesn't look like a parallel-safe issue at all to me, but an exhaustment of your OS, which is not so weird with -j16 on a dual core system? (Resource temporarily unavailable) clearly indicates your OS is protecting itself from going down under the pressure of a fork-bomb. I haven't found any issues with it myself, using -j5, so I'll close this bug as invalid.
