It might be that the smaller-memory machine is swapping until it finally 
runs out of memory.  IIRC, the smaller machine had 1GB and the larger had 
4GB.  So if the memory requirement was 3.5GB, the smaller machien would 
swap memory to disk like crazy before finally giving up, but the larger 
machine would solve the entire problem in core.
