We get the "expected" value from the keys we saved in the now-sorted array, so we do already.

Good catch - My intention was to delete in the same random order we inserted with. We still have the keys in the array, but they're sorted by now. I forgot to go the extra step and use the prng when generating the keys for deletion -- will fix. > --- > The radix tree (and dsa in TSET_SHARED_RT case) should be freed at the end.

I > think it's better to use either one for consistency. Will change to "small", since 32-bit platforms will use slab for leaves. I'll look at the memory usage and estimate what 32-bit platforms will use, and maybe adjust the number of keys.
