The atomic-primops package

[Tags:bsd3, library]

After GHC 7.4 a new casMutVar# primop became available, but it's difficult to use safely, because pointer equality is a highly unstable property in Haskell. This library provides a safer method based on the concept of Tickets.

Also, this library uses the foreign primop capability of GHC to add access to other variants that may be of interest, specifically, compare and swap inside an array.
