Add/remove memory pressure per object

Based on a requested allocation of a managed object, a native memory required with the managed object is determined. A portion of native memory is allocated and a portion of managed memory is allocated based on requirements of the managed object. A memory management strategy is implemented based on the allocation of native memory and unmanaged memory. For example, the memory management strategy can comprise garbage collection of first managed objects that have only managed heap associated therewith is performed before garbage collection of second managed objects that have both managed heap and native memory associated therewith.
