Proposal: Remove Control.Concurrent{QSem,QSemN,,SampleVar,mergeIO,nmergeIO} from base

[Ian Lynagh]

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.

Patch is attached (but basically it just removes the above).


Suggested discussion deadline: Fri 22 June 2012.

Thanks
Ian
