@hackage cfuture2.0

A module similar to the "future" package of Chris Kuklewicz, but having a Future that is interruptible anytime, and easy to represent and handle in C/C++.

It uses two threads, the first of which kills the calculation if triggered by filling an MVar, and the second of which calculating the result and writing it into another MVar. However, the library can be used without manipulating the MVars directly.
