  Serialise making the "sets" tarballs in the maketars target.
  On many systems, making them in parallel causes very poor
  system performance due to disk I/O.  (Requested by jmmv.)

On my development system this adds a lot of time to a release build, and I'd like to revert it. My system is not affected, but if it were I don't see
  why any of these would not be a valid solution:

  o use smaller value for -j
  o analyze the problem on the affected systems
  o buy more spindles

i agree; i didn't like this change when it went in because it also
made my own build slower.

Seems very odd to punish all builders simply because people want to build with -j numbers too high for their system to handle...

It's not like this is a default. You're making a conscious choice to add -j and therefore have to tune what works..
