// This class serves as a Proxy that ensures our process always
// has the appropriate allocator in place for every operation
// that accesses or updates the Map Manager.
//
// = DESCRIPTION
// We need this class because otherwise the ALLOCATOR
// pointer will be stored in the Map_Manager that resides within
// shared memory. Naturally, this will cause horrible problems
// since only the first process to set that pointer will be
// guaranteed the address of the ALLOCATOR is meaningful!

// = The following methods are Proxies to the underlying methods
// provided by <ACE_Hash_Map_Manager>. When they are called, they
// acquire the lock, set the allocator to the one specific to this
// process, and then call down to perform the intended operation.
