I'll use OutOfMemoryError. If any other error occurs, it's probably best 
to let the function fail.

32-bit processes on Windows can only have up to 2GiB of addressable 
memory. Even if there's enough "available" memory, there may not be a 
large enough area of contiguous free space. I've gotten out of memory 
errors when working in D.

I handle the error because I can. My algorithm doesn't require any 
minimum amount of memory to be allocated, so I can reduce the memory 
usage for a small loss in performance.
