A technique reuses addresses in a computer that includes a memory and a translation lookaside buffer having entries for storing address mappings for address translation. The technique involves selecting an address range from a set of address ranges in response to a request to allocate a portion of the memory of the computer, and to generate an address mapping which maps that address range to the portion of the memory. The technique further involves accessing at least one but less than all of the entries of the translation lookaside buffer in response to the request, and later deallocating the portion of the memory. The steps of selecting, accessing and deallocating are repeated such that, when a repeated step of selecting selects a previously selected address range, previous successive steps of accessing ensure that any address mapping, which maps that previously selected address range and which resides in an entry of the translation lookaside buffer, is unavailable for a subsequent address translation.
