In the other direction, the biggest problem is when you explicitely 
unmask a specific version (echo "=dev-db/mysql-5.0.9-alpha ~amd64" >> 
/etc/portage/package.keywords) and then there's a minor upgrade 
(=dev-db/mysql-5.0.9-beta), and the version you unmasked is thrown out. 
Doing a blind -uD will downgrade to the latest stable version in that case.
Of course, the answer here is to use -p and unmask the new versions 
before proceeding. And you can mask the old ones to guard yourself 
against accidental downgrading. (echo "<dev-db/mysql-5" >> 
/etc/portage/package.mask)
