Interesting thing about "recent" changes in GHashTable

Hi,

Looking for some stuff in glib sources, I had found that glib 2.30[1] has nice feature of GHashTable.
If we pass the same pointer as key and value, memory usage is cut down by 1/3 (cool!).

Implementation of it would be a little hacky, but maybe worthy?


[1] Exactly speaking of this commit:
