Yes, the main reason we haven't been storing them in the textcache is
because of the size.  Storing all the text (uncompressed) would nearly
double disk usage for mail.  

Also, the way the Evo mail backend is written right now and because of
the way we have to access Evo's mail stores, there isn't an easy way to
do a quick lookup of mail.  My hope had been to get Evo fixed so that we
could quickly jump to the actual mail and extract the snippet, but maybe
going with a compressed text cache is the way to go.

I haven't gotten to reviewing your compressed textcache patch yet, sorry
about that.  I've been swamped with Novell stuff lately.

Thanks,
Joe
