	Well, I kinda figured it had something to do with the data, but
narrowing it down (500+k records) is something that isn't that easy :(

	I know its the radhist_userid index, which is indexed on one
field, userid...if there was some way of translating location in the index
with a record number...?

	Oh well...will continue to investigate and use your ideas...
