[R-SIG-Mac] R multi-cpu and 64 bit

[elw at stderr.org]

Using SNOW, or MPI, or some careful batch programming to split up your 
tasks across CPUs - yes.

This is the same sort of thing you'd likely face in Stata -- unless 
they've invested a HUGE amount of effort in making threaded/parallelized 
computations "easier".

generally it makes the most sense to leave those optimizations to 
the person running the statistics - they're in a place to 
understand where to optimize things for their problem set.
