This obvious but it just bit me when I tried to spider and check links
on http://www.richarddawkins.net, a rather large site.

I used 64 bit java.exe and gave it 10MB of RAM to play with but it
died anyway.  

One of the problems is HashMaps, even in 64-bit JVMs, can still only
hold 1 << 30 elements.
