Presumably this leads to sparks being created and then immediately going away. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15227 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

We don't use it any more. Let's just add a deprecated note to it and remove it in a future release. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15227#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
