Hmmmm, interesting.  But R CMD install is still fairly slow, right?  I
guess because you're installing directly from the package dir (and not
from a tarball built via R CMD build) it's a bit faster, and only
changed files need to be recompiled.  You introduce a slight risk of
problems caused by build artefacts left by previous runs, but that's
probably worth it for the speed (and you know much more about the
tradeoffs here than I do).
