/**\class AllocMonitorBase AllocMonitorBase.h "AllocMonitorBase.h"

 Description: Base class for extensions that monitor allocations

 Usage:
    The class is required to be thread safe as all member functions
 will be called concurrently when used in a multi-threaded program.

 If allocations are done within the methods, no callbacks will be 
 generated as the underlying system will temporarily suspend such
 calls on the thread running the method.
