It's worth noting that this patch is different from the other mechanical 
patches. I do agree that we should remove this unused portion of the 
slab API. Likely this was built for testing purposes.

CC'ing Junio, who I found introduced this in a84b794ad "commit-slab: 
introduce a macro to define a slab for new type". Looking at that diff, 
the realloc portion did not appear to exist in the previous 
in-degree-specific version of slabs.
