Ouch.  Setting the hash tables was a few seconds instead of instantanous -and-

Mem Usage 48,460 K, Virtual Mem 302,632 K

I switched it back to ''level 0 5 3'' and the memory usage went down to 21,448
K, but the virtual memory went up to 330,316 K.

I sure hope this helps.  I'll try Eugenes code and see if it fixes it.
