Re: Performance Comparison to C in Nested Loops

[Araq]

If you are on a 64 bit machine, Nim's `int` is 64 bits, C's is 32 bits. Use 
`int32` for a fair comparison. Seems unlikely to be the cause of the slowdown, 
but you never know. Definitely an interesting difference to look into. (Factor 
of 3-4 wtf...)
