vector has no default constructor with shared memory allocators (because 
shared memory allocators have no default constructor). So put a 
constructor for PHSharedData

struct PHSharedData
{
    PHSharedData(segment_manager *mngr)
      : CPUTime(mngr)
    {}
    unsigned long TPM;
    phshCPUTime CPUTime;
    phshMemory Memory;
};
