Well, suppose there's just one new message, then surely it can be
inserted in $O(n)$ time, whereas sorting all messages needs $O(n \log
n)$ time, no?

The main time killer (at least for me, I sort messages by number and
use threading but no other sorting -- no scoring or suchlike) is
summary buffer generation which takes the most time.  Thus, having to
generate only a few lines and just sticking them in at the right
positions would be a huge improvement.  I'm talking about groups with
several thousands of (ticked) messages.

Whatcha all think?
