I disagree. By requiring a test run after each change you impose very
high additional overhead and slow down development considerably. No other
project has such requirements. If trunk has 30 changes, and the end result
has good test results, it is a waste of time to run tests on 29 intermediate
states that are not meant to be used.

I'll be merging everything, as discussed later in the thread.
