Comment (by rwbarton):

 I found one cause of leaked `ghc*_*` directories from the test suite:
 `WAY=ghci` tests where executing `main` raises an exception. `WAY=ghci`
 tests are run with ghci input like
 {{{
 :set prog cgrun016
 :set args
 :! echo ===== program output begins here
 :! echo 1>&2 ===== program output begins here
 System.IO.hSetBuffering System.IO.stdout System.IO.LineBuffering
 GHC.TopHandler.runIOFastExit Main.main Prelude.>> Prelude.return ()
 }}}
 If its argument (`Main.main`) raises an exception, `runIOFastExit` calls
 `shutdownHaskellAndExit()` with `fastExit=1`, which just calls `exit()`.
 So, GHC has no chance to clean up.

 This seems like more of a testsuite issue than a GHC issue.

 I'll let the testsuite finish to see if there are any more cases where it
 leaves behind a `ghc*_*` directory.
