Nice enhancement.  This should *significantly* increase the speed of the 
code.  I'd be interested in compiling it and running it through a few 
cycles to see what it can do, when/if you are willing to release it.

For me, the trouble is twofold:  a) as Roy said, I would really like to
see SWISH++ retain the ability to index META tags in a fielded manner,
and b) on a lot of old BSD-like systems, there is no mmap utility.  I
run SWISH-E currently on three different operating systems (Linux,
Ultrix, and Digital Unix.  Ultrix does have an mmap utility, but it 
is non-standard compared to the news sysVR4 stuff... 

Oh well...
