Hi all,

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

Rationale: There is no real need for them to be in base, and they are not being well-maintained there (e.g. see [3160]). Chris Kuklewicz has already made a SafeSemaphore package that provides fixed versions of the 3 modules.

I was going to import Chris's STM versions from #3160 to fix the outstanding bugs, but I'm also fine with removal. We probably should DEPRECATE for a cycle though, tempting as it is to just remove them immediately. Cheers, Simon
