The problem had little to do with crossing between stable and testing:
it concerned the corner case where an installed ebuild has been
deleted from portage.  This non-monotonicity is causing problems.

My suggestion is that -U should mean that what is _installed_ takes
precedence unless there is an acceptable more recent version in
portage.  Whether a version is acceptable is of course controlled by
ACCEPT_KEYWORDS as you suggest.

This means that in the case I reported, it should have left tetex
alone: it should not try to downgrade it because I explicitly supplied
-U, and it should not try to upgrade it to the newer version in
testing because I did not explicitly set ACCEPT_KEYWORDS="~x86".
