That is just a faster version of the wrong thing.
Can you explain what is the problem with an IntPSQ?
This bug was filed because I was working on fixing it correctly.
Nice! If there any possibility we can get a stripped TimerManager(like the IOManager) which use a PSQ per core? It will help under high contention situation s. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12999#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
