The history file is 138MB and the history.pag file in 9MB.  I have always
seen it reply to an IHAVE within 3ms, so I always figured enough (or all)
of the history.pag file is in memory.

Perhaps I need to reduce the quantity of news that I am keeping to fit
within my current memory.  I will be upgrading from 32MB to 128MB in the
next couple weeks, but the memory won't arrive soon enough.

Thanks for the info!
