Abstract: Methods of memory management in a run-time environment are described. A mechanism is provided for registering a routine to deinitialize or deallocate a large object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the large object from being migrated into session memory, e.g. when live objects are migrated at the end of the call. This routine is called after the finalization of garbage collected objects that may use the large object. In a subsequent call, the large object is checked before use to determine if the object is deinitialized and re-initialized if the large object was deinitialized.

Abstract: Methods for managing memory in a run-time environment are described, in which an object is activated by both initializing the object and registering a routine to deallocate or deactivate the object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the object, which may be a large object, from being migrated into session memory. This deactivation routine is called after the finalization of garbage collected objects that may use the object. In a subsequent call, the object is checked before use to determine if the object is already activated and re-initialized if the object is not activated.
