[R] Slow reshape from 5x600000 to 6311 x 132

[Christopher Austin-Lane]

Thanks for the info - it inspired me to keep tweaking.

R --min-vsize=400M --min-nsize=6M

allowed me to run in a few minutes - I had been trying larger values of 
--min-vsize (600M) (I have 1 Gig of RAM, but a lot of stuff running), 
but that was evidentally causing R to swap during the reshape, which 
caused it to really slow down.
