I dont know if this will help but Ada 83 & 95 provided private memory pools. I
cant remember the exact syntax however in essence you specify the amount of
storage to be used for a private pool for a particular access type. When an
object is created via new the memory is taken from the private pool not the
heap. This would require you to create a private pool for each access type.
This is briefly covered in Barnes somewhere.
