MANAGING TEMPORAL DEPENDENCIES BETWEEN SETS OF FOREIGN RESOURCES

Techniques for managing temporal dependencies between sets of foreign resources are disclosed, including: allocating, in a runtime environment, a segment of foreign memory to a first memory session, the runtime environment being configured to use a garbage collector to manage memory in a heap, and the foreign memory including off-heap memory that is not managed by the garbage collector; opening, in the runtime environment, a second memory session that descends from the first memory session; while the second memory session is open, encountering a request to close the first memory session; responsive to encountering the request to close the first memory session, determining that the first memory session has at least one open descendant memory session; responsive to determining that the first memory session has at least one open descendant memory session, declining the request to close the first memory session.
