My proposal is for the expert and not at the CLI level.  Something
like "(funky-name ghc-foo)" which returns a new package with
PARALLEL-BUILD? turned to #t.  And the default should be #f.  WDYT?


Well, I am going to try to rebuild the packages with #f and see if it
fixes the ~300 unreproducible packages.


Cheers,
