[R-sig-Geo] Subsetting RasterBrick very slow

Christian, 

Thanks for reporting this. I have improved the subset routine in raster
version 1.8-39 (on CRAN now for linux, but not built yet for win and mac).
In some cases nearly 1000x faster, as you also reported, but other cases
need further optimization. 

Best, 
Robert
