New description:

 If we could somehow reduce the memory used by the postlist changes chert
 buffers, we could buffer more and/or let the OS have more spare memory
 for buffering disk blocks.  That should allow indexing to run faster.
 However we need to compress in such a way that we can still implement
 Xapian::Database methods including the effects of the buffered changes.

Comment:

 Update to refer to chert rather than flint or quartz.
