In particular, daily snapshots are usually only tested on the machine
of the last person to commit code to the repository. One of the main
points of having the test periods before release, and the associated
code freezes, is that this allows a reasonable chance that the released
sources work across a range of platforms. (The other reason is that it
prevents developers from rushing in changes.)
