Abstract
A mechanism is provided for leasing fragmented storage between processes. The mechanism comprises a fragmented memory manager associated with instances of virtual memory managers to provide a pool of memory that may lease from the owners of the memory and in turn sub-let the memory for use by other processes or owners. The mechanism allows programs to operate under normal conditions until fragmentation sets. A different memory manager leases those fragmented memory blocks from processes to create a virtually contiguous block of memory that it can sub-lease to processes in need of temporary expansion beyond the memory available for the processes under normal circumstances.
