The idea discussed in ESC was to allow developers to write tests for
bugs, even if they are not able to fix them. We also assumed / hoped
it's easier to write a test then fixing a bug. We'll see, if this turns
out to be true.

Most times this feature is used for test driven development, where you
mark tests as expected to fail without breaking the build and when you
actually fix the bug you simply remove the XFAIL from the test case. The
idea is to prove you wrote a test for your bugfix.
