HASH-TABLE-WEAK-P is fbound, but the docs only mention weak pointers, 
and just passing e.g. :weak :key to make-hash-table doesn't seem to work.

(N.B. This is another area where a little additional standardization 
wouldn't hurt IMHO.)

No, it doesn't. The few references to weak hash-tables in the
internals are just remnants from old CMUCL code.
