If it were a frequent occurrence, there may be some benefit in that. But using only one of the CPUs 8 cores is such a waste when this sort of thing happens only every few weeks. Usually trying again works, rarely does using -j1 make a difference and when it does a bug report ensures that it won't be an issue in future. --=20 Neil Bothwick PROSTITUTE: Receiver of swollen goods. --Sig_/vsx8K1ZIUSifl1JRg.UngCv Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) iEYEARECAAYFAk9Go9cACgkQum4al0N1GQPXjgCbBJ0fYsXFDH5EBaLerB5x1yXa usYAn3yqhgLLBflMqfUtOufTljKy9+sL =ek6c -----END PGP SIGNATURE----- --Sig_/vsx8K1ZIUSifl1JRg.UngCv--
