Phase post-integration-test not executed when tests are timed out with option 'forkedProcessTimeoutInSeconds'

In a project we use the failsafe plugin for our ITs.
The option 'forkedProcessTimeoutInSeconds' is used to have a time limit for the test execution.

<configuration>
	<forkedProcessTimeoutInSeconds>3</forkedProcessTimeoutInSeconds>
</configuration>

We also have goals registered in the post-integration-phase for environment clean-up.

When the tests are in timeout, the maven execution is stopped and the post-integration-test phase is not executed, leaving our environment dirty. The post-integration-test phase should be executed after timeout the same way it is executed after failed tests.

Attached is a simple project illustrating the issue:

• a JUnit test that runs forever
• a goal is registered in the post-integration phase
• the timeout is set on the project

If you run it, you will see the post-integration-phase is not executed:

As a side-note, if we set the forkMode option to 'always', then the post-integration-test is executed even if the timeout expires. But there are some Java processes for the tests (the one running surefire-booter-*.jar) that are not killed. There seems to be an already opened issue for that (http://jira.codehaus.org/browse/SUREFIRE-773).
