His change is only appropriate for the WeakIdentityKeyDictionary, not 
the WeakKeyDictionary. Because the *Identity*Dictionaries use the 
object hash, and the hash is only 12 bits, we need to spread out the 
coverage when the collection is more than 4096 long.

You will find identical code in the IdentitySet and the 
IdentityDictionary.
