/**
 A simple implementation of thread safe mutable dictionary.
 
 @discussion Generally, access performance is lower than NSMutableDictionary,
 but higher than using @synchronized, NSLock, or pthread_mutex_t.
 
 @warning Fast enumerate(for...in) and enumerator is not thread safe,
 use enumerate using block instead. When enumerate or sort with block/callback,
 do *NOT* send message to the dictionary inside the block/callback.
