In the 0002 patch I introduced a macro for building an abort command
in preparation for the parallel abort patch (0003), but I moved it to
0003.  Attached is a new patch set.  The new version of 0002 is just a
cleanup patch (see the commit message in 0002), and I think it's
committable, so I'm planning to commit it, if no objections.

Best regards,
