Comment:

 This is pretty much required by the standard, which the library follows.
 If you want to avoid it you have to either use an alternative allocator
 which doesn't use malloc (although, reportedly that doesn't result in much
 of an improvement) or use an alternative hash table implementation. You
 could use the intrusive library or google's dense hash map. There might be
 others.
