Comment (by alpmestan):

 Oops, forgot to include it in my previous comment. Here's what I get for
 say the 'ghci' way (same for threaded1 and threaded2 though):

 {{{
 =====> T8089(ghci) 1 of 1 [0, 0, 0]
 cd "../../libraries/base/tests/T8089.run" && "/home/alp/ghc/inplace/test
 spaces/ghc-stage2" T8089.hs -dcore-lint -dcmm-lint -no-user-package-db

 T8089.genscript
 Wrong exit code for T8089(ghci) (expected 99 , actual 0 )
 *** unexpected failure for T8089(ghci)
 }}}
