There's a USENIX'92 paper that describes Purify:
                Reed Hastings and Bob Joyce. Purify: Fast Detection of
                Memory Leaks and Access Errors. Winter USENIX Conference '92.


                You might also want to look at a paper by Todd Austin & co
                in PLDI'94 which describes Purify and other run-time memory
                checkers in its related work section.
