Thanks a lot for the confirmation folks. I simply found a way round
the problem in the meanwhile. My application was such that I could
know the boundaries of the image in terms of lat/lon without actually
reading the complete image. What I did was to get this information for
small rectangular chunks of image in a 2D loop at using the region
keyword and then use these smaller images as complete images only if
it was useful.

But choosing an optimum tile size has been a problem and it still
causes upto 4 times the memory strain than reading just the right tile
would have caused. What would I have done without my 2GB RAM!

Cheers!
