Detailed Description
template<typename T>
class thrill::common::AtomicMovable< T >
This is a derivative of std::atomic which enables easier and less error-prone writing of move-only classes by implementing a move constructor.
std::atomic does not have a move constructor for a good reason: atomicity cannot be guaranteed. The problem is that then all move-only classes containing a std::atomic must implement custom move operations. However, in all our cases we only move objects during initialization. Custom move operations are trivial to write but error-prone to maintain, since they must contain all member variables. Missing variables create very subtle bugs, hence it is better to use this AtomicMovable class.
