TODO

1. Multithreading
     - Idea is to open 2-16 threads depending on core count and then pass a
       mutex between them. They will share the element pointer, counter pointer,
       and any other IO stuff. Those will only be accessed in the mutex. Also,
       we should be doing the unlocking/relocking in that mutex so that the
       all the threads stall while we let other things run. Maybe we should have
       two mutexes, 1 for reads and one for writes, since I think they can
       happen at the same time.
2. Pagination
     - We should do pagination redis side so as to avoid doing extra work. Maybe
       doing it with threads would be neat (e.g. a thread every 2xpagesize entries)
3. Memory management
     - We are almost certainly not deallocating memory as we should be. Let's
       fix that.

BUGS
  - So far so none
