Detailed Description

template<class MutexType>
class MutexArray< MutexType >

A mutex array protects a number of resources with a limited amount of mutexes. It uses hashing to find the mutex of a particular object. The idea is that if the amount of threads is much smaller than the amount of mutexes that there is a relatively small chance that two different objects map to the same mutex.
