For my (and other's) education, can someone explain to me why you would want to hash a pointer? Google let me down.

It is probably not a common use case, but in applications such as garbage collectors, interpreters, allocators, some kind of caches, etc... you may want to keep track of a set of pointers in a hash table. Hence you need a hash function.
