Well, of course we know about this problem in general.  And trust me
that it has been worse two years ago :)   Linux has a very superb
caching for the filesystem, while we have no equivalent caching (we just
have the pager).  However, I was wondering about whether this particular
sequence of commands requires disk activity.  Maybe it's just a bug
somewhere that can be fixed.

Implementing a proper caching strategy would be a very good task, but it
is not easy.
