Agreed that this case is possibly slightly different - however this
change is merely exposing already flaky tests - and this change is very
much overdue. If the tests mentioned are really that important, then
could we please get people allocated to fixing them? You can't exactly
say that Joel hasn't given sufficient notification to the lists & yet
we've had virtually no interested in resolving the issues.

The policy does state:
"In the rare case we are disabling the majority of the tests (either at
once or slowly over time) for a given feature, we need to get the module
owner to sign off on the current state of the tests."
However it intentionally doesn't state it for smaller cases (I'm not
including the above in this). Ultimately disabling a test is a last
resort, and if done according to the policy, will have been performed after:
"In the case we go another 2 days with no response from a module owner,
we will disable the test."
...in which case either the module owner will ignore the review request
(which makes the policy pointless, since the whole idea was to set
expectations and consequences that would actually be enforced), give it
r- (which isn't acceptable, given they've not acted on the bug in a
reasonable timeframe), or give it r+ (in which case, great, but this is
the state we should be in anyway).
Ultimately no one individual test should have the right to destroy the
SnR for a suite - and if we don't have this policy as a rapid (and
enforceable in practice) means to control rogue tests, then the only
other hammer the sheriffs have is to hide entire suites.
