Status in NUnit V2 Test Framework: Confirmed

Bug description:
NUnit 2.5.2 and 2.5.3 run every method targeted by TestCaseSource, even if the test targeting it is Explicit or the test fixture is Explicit. 

The behaviour I expect is: NUnit shouldn't run a test's TestCaseSource if the test itself won't be run.

Detail:

I have an expensive TestCaseSource generating a few hundred thousand permutations and combinations. I've applied Explicit to both the test targeting the source and the fixture surrounding both test and source. 

NUnit console spends ten minutes needlessly constructing test cases from the TestCaseSource before ignoring them and proceeding with the non-Explicit tests. 

If I throw NotImplementedException from the first line of the expensive TestCaseSource. NUnit runs the non-Explicit tests immediately. If I put a MessageBox.Show call in the first line, I see the message box.
