With DUMPSTYLE set to 9 (compressed selective dump to the system disk 
(with full console output), it wants the dump file to be somewhat less 
than half the size of physical memory, with the fraction decreasing with 
the size of physical memory.  This feels about right, but I don't 
understand the fine-tuning.
