SUGGESTED FIX

I implemented my own quicksort that does a full 32/64 bit swap instead of byte-by-byte swap. 

I ran this for 65 hours on my wokstations without a crash.

On my laptop I ran it for for 66 hours straight. This build has the extra fix that sorts each method array 2000 times. With the stdlib:qsort() this crashes within 1 minute.
