Memory management techniques

A computing device having instructions stored therein for performing operations that manage memory allocated to one or more processes executing on the computing device, the operations comprising:

• maintaining a record of allocated memory space for which contents of the allocated memory space are not required to be preserved, the maintenance of the record including:
• removing an identifier of a first memory space from the record in response to a request from a first process to use content of the first memory space;
• detecting that the computing device is experiencing memory pressure;
• selecting, based on the record, a second memory space for which the content is not required to be preserved;
• and
• ceasing to preserve content of the second memory space.

A computing device, comprising:

• at least memory device;
• and
• at least one processor, wherein the at least one memory device and the at least one processor respectively store and execute instructions, including instructions that cause the at least one processor to manage memory allocated to one or more processes executing on the computing device, the management of the memory comprising:
• receiving from a first process to which first memory is allocated an indication that the first memory contains first content that is available for discard;
• subsequently receiving from the first process a request to use the first content of the first memory that was indicated to be available for discard;
• determining whether the content of the first memory was discarded;
• and
• based on a result of the determining, responding to the request with a notification that the first content is available for use or that the first content was discarded.
