A method for managing memory freed by processes executing in a virtual memory space in a computer system implementing means for mapping virtual memory addresses into physical memory locations accessible by an operating system (O/S), said method comprising:
receiving, by said O/S, an indication of freed memory in said virtual memory space that spans one or more fixed size memory units in physical memory; and,
adding said fixed size memory units to a free memory pool, said fixed size memory units in a free memory pool being directly allocatable to a process requiring backing physical memory store without the O/S deleting data in the freed fixed size memory units.
