Argon2 in Pure Nim.

Sorry to belabor the point but getting this right is important to me and I am 
unable to verify what you guys are saying. I really can't see how using 
createThread is giving me the WRONG number of threads. From the documentation:
    
    
    import std/locks
    
    var
      thr: array[0..4, Thread[tuple[a,b: int]]]
      L: Lock
    
    proc threadFunc(interval: tuple[a,b: int]) {.thread.} =
      for i in interval.a..interval.b:
        acquire(L) # lock stdout
        echo i
        release(L)
    
    initLock(L)
    
    for i in 0..high(thr):
      createThread(thr[i], threadFunc, (i*10, i*10+5))
    joinThreads(thr)
    
    deinitLock(L)
    
    
    Run

The code explicitly creates 5 threads. Running the code results in 5 threads 
being created. So this seems to be working exactly as expected?
