Anyone building with a new enough glib will get this behaviour for free? So I don't think it's worth backporting to older builds unless the memory savings are really significant...

Very neat optimization though.

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?
