Abstract
A method of allocating regions of memory including the steps of allocating a corresponding plurality of portions of memory for use by the process and marking regions of memory that are allocated with markers. A start of a region is marked with one of the markers and an end of a region is marked with a further one of the markers, the further one of the markers having a later relative time indication and marking a next allocated region. In response to determining that a region of allocated memory bounded by two of the markers is no longer required by the process, deleting an older of the two markers; and in response to detecting deletion of an oldest one of the markers, deallocating the region of memory up to a new oldest pending marker.
