My thinking was the following: the test framework is a core thing, if
someone breaks it then we can end up with the situation where tests
can no longer be run. The build system is something that users rely

Most of the time I don't write a patch and commit it the same day. I
write and test it on FF one day (at home), and test it on IE and mark
it as "Review" the day after.

I understand your concern with slowing down development. But I agree
with Tim that it's great to have a reliable trunk. I'd just like to
see it as reliable as it is today.
