I propose that we remove Control.Concurrent.QSem Control.Concurrent.QSemN Control.Concurrent.SampleVar Control.Concurrent.mergeIO Control.Concurrent.nmergeIO from base.

I've just deprecated them for now, with a message saying they'll be removed in GHC 7.8, and pointing at SafeSemaphore.

Cabal uses QSem

You mean cabal-install rather than Cabal, presumably?

so I think we'll have to merge in some code from SafeSemaphore as we cannot depend on that package.

Why not? It's the same code, regardless of whether it is in base, cabal-install or SafeSemaphore. Looks like SafeSemaphore has almost the same module names too. Thanks Ian
