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;
};
