Actually, it makes it faster. If you mmap the image to a base address  
that is likely to be available the next time around, then you avoid  
the oop relocation on startup which touches the whole object memory.  
Thus image startup becomes blindingly fast since the pages do not even  
have to be loaded from disk until used.

(You also have to disable the nonsensical check for finalization  
support, every VM made in the last 5 years supports it, and it's  
forcing a full GC on startup.)
