/*
 * These are some simple generic hash table helper functions.
 * Not necessarily suitable for all users, but good for things
 * where you want to just keep track of a list of things, and
 * have a good hash to use on them.
 *
 * It keeps the hash table at roughly 50-75% free, so the memory
 * cost of the hash table itself is roughly
 *
 *	3 * 2*sizeof(void *) * nr_of_objects
 *
 * bytes.
 *
 * FIXME: on 64-bit architectures, we waste memory. It would be
 * good to have just 32-bit pointers, requiring a special allocator
 * for hashed entries or something.
