commit c271e32eac65ee95ba1aacc72ed1b24b58ef17ad Author: Joachim Breitner Date: Sun Jan 26 11:36:23 2014 +0000

Add GHC.Prim.oneShot

to allow the programer to explictitly set the oneShot flag. This helps with #7994 and will be used in left folds. Also see https://ghc.haskell.org/trac/ghc/wiki/OneShot

This commit touches libraries/base/GHC/Event/Manager.hs (which used to have a local definition of the name oneShot) to avoid a shadowing error.

Differential Revision: https://phabricator.haskell.org/D392
