havent we just removed our custom SLAB allocator recently because it 
wasn't worth the maintenance effort?

we have --with-alloc configure flags but setting that to anything custom 
like tcmalloc or jemalloc was removed in 
494bdd3dc32287cc01ea4e0d81438a9266425726 because it had been broken 
since 2011 and nobody noticed.
