management are described.

The method also includes recording,by a memory management unit, a mapping between the virtual memory page and aphysical location in a memory. The method also includes in response to a request, fromthe application, to deallocate the memory buffer, delaying invalidation of the mappingbetween the virtual memory page and the physical location in a memory, based on acount of free frames in the address space of the application.
