Allocate lots of memory => core dump

I'm sure that there are people here more knowledgable with I, but I believe 
that the per-process memory limit is 3GB with 2.4 kernels, Windows XP pro, or 
win2k adv. server, and only 2GB per process with 2.2 kernels, Windows 2k Pro, 
etc. (on ia32 machines).

I'm not an expert on this, though, so YMMV, but we've been running into this 
ourselves under different circumstances.  Specifically, I don't have any 
experience with >4GB IA32 boxes.
