HIGH-LEVEL SPECIFICATION: With custom memory allocators, using the Valgrind APIs we can tell Valgrind when a memory block is allocated (so that data read from memory is marked as undefined instead of being defined or not at random depending on prior use); and when a memory block is freed (so that use after freeing can be reported as an error). In some cases cheking for leaks may also be appropriate. Another possibility is to add an explicit check for whether memory is defined. One place this would be useful is when calling libz.
